2008 Electrical Issues: TPMS, dash lights, blinker, etc
I'm new to the forum, and I'm hoping you can help.
I recently purchased a 2008 Rubicon Unlimited with about 66k miles on it. When I test drove it, the TPMS warning light came on. It went off shortly after I started driving and I assumed a tire had been low; the dealer aired it up; no worries. The light never came on again during the test drive of about 15 minutes.
After buying the Jeep, not only does the TPMS light continue to come on, many other warning lights randomly come on as well including:
In addition to the warning lights, the left turn signal push to flash function doesn't work (push it and it blinks 3 times). The horn doesn't work, and the right rear power door lock doesn't work.
So far, I've disconnected the battery and touched the cables together; run a dedicated ground from the battery to one of the grounding lugs by the TIPM; and today I put a brand new TIPM in it. No change in the symptoms.
I'm guessing the clock spring could be bad, but I don't know if that accounts for all the issues.
Any help would be appreciated.
