Two days ago, I turned on the windshield wipers on, and all I got was some clicking in the seat belt system, and the roll bar light came on.
The wipers don't work in either position (I, II, III or push-in for wiper and wash). My washers haven't worked in a while (some kind of leak in the piping), but the wipers themselves have worked perfectly as recently as 2 weeks ago.
A little background:
A couple of years ago, I had a problem with a bunch of systems not coming on line, or acting up when I would start the car. The Command would cut out, the seat heaters, wipers, seat memory, steering wheel positioning, would not work, and the roll bar light & airbag light on the glove compartment would flicker and the seat belt lock would click rapidly. But it would be intermittent. Then I found that if I tapped on the key a few times while it was on, everything would "reset" and work until next time (usually next time I had to start the car).
All this pointed to the EIS, so I had my mechanic remove and clean the EIS, all the contacts, etc. That fixed all the problems... until the other day.
While I was driving I tried to turn on the wipers, and the familiar roll bar & airbag lights, along with the seatbelt clicking came back, and the wiper didn't move. When I turn the wipers off, the lights go out, and the seatbelt soft release works OK, no clicking. All the other systems work fine, just not wipers.
I thought it might be the same issue as before, so I had the mechanic pull out the EIS, but he said it was clean and he even tried cleaning it some more, but it didn't fix it. So he suggested that the issue might be in the driver side SAM, of which I happen to have a spare. I replaced the SAM, checked all the related fuses (F1 & F5) and relays (A, G & H), but to no avail.
So now I'm left wondering what might be the problem. I don't think the motors die just like this, overnight so to speak, even so, I plan on checking it this weekend.
I know there are 4 wires that connect to the wiper motor, but I don't know what they are, or what volt5ages I should see if I put a volt meter on them Does anyone know what to look for at the wiring harness (what the wires are)?
I assume that if I find voltage on the wire, then the problem is the motor, if not, where do I go from there? Rainy season is coming to No. California, and I'd like to get this fixed.
PS. This is a 2005 SL500 w/rain sensors
