Thanks for the reply Ruffneck. Are you referring to this gadget?
Because this is what my Haynes
manual and Autozone
say the ESC module is. You're right. It is on the passenger side, near the air filter. Actually, finding it is not the problem. Determining its functionality and troubleshooting it IS the problem. I've been looking for a wiring diagram or schematic that shows how it is wired into the system. I have found a couple write-ups online that explain when it is used or bypassed by the computer, but a schematic is worth a thousand words.
What I've found so far is pointing to my ESC module (or its wiring) as possibly being defective, but I'd like to "test" it in some way so that I can be more definite about my conclusion before I lay down $70.00 for a new one.
Have you found any good online sources for schematics and such?
