JK:
Hello and welcome. First things first. Be sure that the batt. cables are tight, and check all
fuses. These different problems could be a wiring problem somewhere.ground problem.
Nothing common comes to mind. could also be a pcm(computer) or pcm connector
problem. Need to get the system scanned for codes in order to an idea of what is going
on. Before that, you could disconnect the pcm connectors(with key off) and look to see if
any corrosion in pcm or connectors.
It is under the hood, near the pass. side top of strut tower. Let me know what you find,
thanks.
