Several problems to sort out

Okay here we go. I have a 2001 e320 v6 that that i purchased 6 months or so. I have a list of issues that are common but i havent corrected with common procedures and then some issues that i cant find much info on.
1..To began with I have the abs/bcs lights. I replaced the brake light swith to no avail. I will mention the car has aftermarket disk brakes that where on the car when i got it.
2..There is I believe an electrical problem of some sort. During regular driving the a/c will stop blowing and simultaniosly the blinkers will stop if I am using them when the a/c quits. I can hit on the the dash just below the glove box and generally it will all come on. Although probably a whole diffrent problem the windshield wipers only have two modes (medium/fast) the slow intermiting speed will some times not work at all , then it may match the medium setting and every now and then it will work correctly. Also under heavy acceleration the a/c-blinker problem will occur and then under braking it will work again(i can almoht make it happen at will)
3.. I also have an issue with vibration.Yes i have read stickies on this subject. It will run smooth when first started but once warmed up during driving it will run rough when at a stop sign/light but clear up just under 1000rpm. I replaced the driver side mount because it had major slop but not the passenger it has some motor movement but not near as much as the old one. This has not corrected any vibration. I have thought about ordering another for the passenger but got discouraged from the other not helping at all.
I have been curious if all of these problems are from a motor ground issue and related. Any insight would be helpfull and let me know if i have confused you or you need more information.

1 and 2 may be related, you may have a ground issue under the dash that could account for such behavior. The wipers might also, or that might be related to the switch. Investigation is the way to start, I think, but one thing to do is start watching the voltage, you can do it from the HVAC controls and watch for spikes or drops.

3...you're applying Ford logic to MB. "Sloppy" is meaningless with a hydraulic mount. Once they leak, they settle, and you get the vibration. I don't know if you looked in the stickies, but did you see those side-by-side shots? Replace the other mount. And do the T mount while you're in the process, it's easy and quick and pretty inexpensive. Just don't buy a URO. It that a guarantee to fix the vibration? No. But it's the first and best place to start based upon your description of it.

Good luck.
