Let me start with saying these issues come and go with no rhym or reason.

1. With the wipers turned off they will start running fast and to turn them off I just turn the nob once then they stop. Sometimes even doing this does not work and I will be driving down the road on a sunny day, which doesn't happen very often, with my wipers running. But since the new issue below showed up my wipers are working great.

2. My keyless entry system stop working. So then I used the mental key and went and open the trunk which I guess resets it. Now that is working fine.

3. Since the reset of the keyless entry my radio now has no sound but my wipers are still working normally. Mute button show up on the screen when it is pushed. There is just no sound coming from it.

4. I kept the Star Tac in its cradle and on but now it will not power on since all this happened.

So any suggestions on how to get the volume back onto my radio, while keeping the keyless system working, and not have my wipers go on whenever they like?

Thanks for the help!!!

Did you just get the vehicle? and have you read your manual thoroughly? they are all un related. unless you have gremlins. when you play you figure it out. the wipers could have been on rain sensor as that would explain the one all of a sudden. Is your radio in phone mode. It sounds like the old chrysler K car turn the lights on and the radio goes off. Start with one problem exclude the others that work from your question and work from there.

this could be a sam problem.

Given that you've had a lot of rain, have you had any water intrusion?

Found another problem!

I have had the car for about 1 1/2 years. I bought it from a Nike executive who only drove it to and from the airport and it only had 27K miles on it when I got it. It was like brand new and for an 8 year old car perfect condition.

I have read the manual from front to back.

Wiper sensor, correct me if I am wrong, should work when you turn the wipers on to the first position. My problem was when they were turned completely off.

The radio might be in phone mode but since the phone won't work or is dectected by the car how would I get it out of phone mode?

I agree all these items should be unrelated and just might well be but it is strange that when one problem stops a new one come up and I mean right away.

Oh and here is a new one I just noticed, when I get out of the car at night the lights come on, which is what they are suppose to do but now they blink and go into high beam. It doesn't happen all the time but just most the time. This started on last Sunday.:crybaby2:

I will post the car history as I know it.

Thanks guys for all the help!!!

That was a great discription, and helps allot. i agree with Oliverk sounds like your sam problem, I feel bad for you because the vehicle sounds like it was a super deal. have you washed it in a car wash or with high pressure water? or drove through a really big puddle lately.

Not that I can think of. I have been getting my car washed at the local drive threw wash since I have had it.

What is the SAM?

 

[Quadcammer]

SAM is signal acquisition module.

Basically, the s class is unlike many other cars that have separate computers for each electrical item.

Basically, on the MB the SAM is where a bunch of different inputs are wired into, and it controls all of them through the Can-Bus.

So if say one were to get wet, a lot of odd problems can occur.

 

[Gammaess]

if you get water in the gremlin house aka SAM you have a headache. I only wash mine by hand, there are a few threads in here about this issue.

 

[NWS430]

Were is the sam located in the car?

 

[Quadcammer]

I believe under the front seats for the front sam.

I believe its the passenger side, but Im not certain.

 

[NWS430]

A nother problem has come up today! Anybody want to sell me some swamp land?

I believe under the front seats for the front sam.

Thanks I will check it out

NEW PROBLEM TO ADD TO THE LIST:

I was driving the neighbors to the airport today and half way there I started to feel a vibration like a tire was going flat. I was getting off at the next exit when it stopped shaking then 5 minutes later started to shake again the I hear a thud and the vibration stopped and has not come back. So I dropped the neighbors off and then stopped at Costco. I went to go set my parking break, which I do out of habbit and the damn pedel went to the floor. My breaks are working just fine but no parking break now.

Can anybody think of what might have happened?

Thanks for all the help!!!

 

[Gammaess]

Did you forget and leave the hand break on? Man I feel for you, you are having a hell of a time with this car, I can see how you are going nuts. Well if your emergency break is going to the floor with no lock up. trace your cable and see if it had snapped and take a good look at your rear disks and pads, just because you have brakes may be just your front ones hook up.

 

[Magnified]

cable snap on the brake, or fastener broke off. At first I thought a weight came loose until you said the pedal went to the floor.

On the other issues, sounds like the SAM, but I thought I would throw this out there too: On both my GTO and my wife's Jaguar, the car does weird things if the door is opened while it is locked, or it is locked/unlocked in a strange combination. In the Jag, this anti-theft confusion has disabled the radio/nav done other weird things. However, in both cases, it's cleared up when I've turned the car on and off through one cycle and then locked and unlocked it in the conventional order (close door, hit remote, hit remote, open door).

Hope this helps,

Just an idea on the radio... I can give you more details if needed. Does it show up and say no CDC or No phone? if thats the case something in your fiber optic loop is down. You can buy a bypass coupler, $6.00 from dealership, and bypass each component until the system comes back.

 

[NWS430]

Thanks I will try that and let you know.

I believe under the front seats for the front sam.

I believe its the passenger side, but Im not certain.

there are 3 sam modules in the car

1 under the passenger side rear seat

2 on opposite sides of the engine, if you pop your hood and looking at the car there are in the top left and top right boxes, one of the boxes should have a sticker and say battery in trunk. there are other computers there but the sam is the computer connected to the fuses and disconnects from the fuse box.

if you think its your sam i would take a look and see if you find any water or corrosion on the connections on all the sam's. but make sure your disconnect your battery before disconnecting anything

 

[Gammaess]

Certain sam's control certain functions, check your fuse functions beside the sam's and see what are in those banks and that will give you an idea from which one is giving the problem? I think that is how they work but not sure. but as ekbenz said disconnect battery before mucking with those. A good tech should be able to check them out pretty fast and see if they are green , corroded and lube if that is the problem cheap. and by asking him to check them he knows that you have some idea of your problem.

 

[NWS430]

Thanks I will check out the SAM's tomorrow.

Anybody have diagrams of the emergency break system? I would like to track this down before I climb under the car.

Thanks for all the help!

 

[ekBenz]

what i would do in your case, i am a little mechanically inclined

take off the kicker panel on the left side of the footwell, there is a screw in the middle right thats a little hidden but its there, dont forget to disconnect the tweeter down there (yeah theres a speaker there)

then track down the cable and try to follow it under the car

im dont remember if you have to take off the underbody plastic panel or if its exposed

and if you cant see anything wrong

next step is to take off you rear wheel, you can do one then the other if you dont have jack stands

unscrew the caliper, 2 bolts behind the caliper, you need a long thick screw driver to decompress the caliper a little to take it off the rotor

then unsrew the bolt holding the caliper ( im not sure if its there or if thats only in the front, but if you look you will deffinitly see it if its there)

then try to take of the rotor, if its a little rusted around the center hub, my technic its to spray WD-40 around it and hit around the rotor a little, not the disk part, and the vibrations will usually get it off

then once you have it off then see where the cable pull and see if you see anything broken or bent.

this might be too extensive but if you would want to sace some money then this would be a good way to go

Thanks for the help. I am not able to work on the car for a few days due to all this global warming we are having here in Seattle. It's snowing like crazy right now at my house. Good news is it shouldn't stick around. We are suppose to have sun this weekend. Can anyone here tell me what that looks like?

When I do get a dry day I will post what I find after trying a few of the suggestions here.

Thanks,

Paul
