2005 chevy Cavalier. Car is running hot,ac cycles on and of, transmission shifts hard on occasion ,electric fan starts and stops.
Answer: First things first. Be sure that the battery 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 passenger side top of strut tower. Let me know what you find, thanks.
