Unhappy Help, ACC Servo current draw

I finally found my what was causing my battery drain, it is the dreaded ACC Servo. I found that there is a draw comming from the purple wire, but I havn't traced it to it's orgin yet, but I am going to guess that it leads the to control amp??? If so, does this most likely mean that I need to replace the control amp, or might there be something else that is causing the problem draw... All I really have to work with is this forum , and my trusty Chiltons manual

Hi Eric , try resoldering the acc amp , the short maybe inside it . I resoldered mine last year and it was easy . Pull the glovebox and it's right behind it to the right .Good luck .

I just pulled the acc amp, and I found that it was made in Mexico . There are a bunch of burnt marks on the circuit board, so I am making a wild guess that it is bad, but I can always be wrong...

The burnt marks are the areas where it's been shorting on the circuit board. Carefully resolder the entire board and you may solve your problem , mine still works and it was that bad.Good luck.

I'll give it a try one of these nights, it would be very nice if I can get the thing to work again, without having to spend a lot of money to buy a new one...
