2005 chevy Cavalier.
Car is running hot,ac cycles on and of,
transmission shifts hard on occasion ,electric
fan starts and stops.
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.
