I vote for the fan motor. My '94 was overheating for months, tried everything, even wired a switch to turn the fan on when temp started to rise. The fan worked fine when the engine was cold. Then, when it overheated on a hot afternoon, I switched it on and it continued to overheat. I looked under the hood and the fan was barely turning over!

A replacement fan assembly is cheap, or just pick one up at the junk yard. Be sure it's working when the engine is hot - way to tell, turn on the AC. Even if the temp sensor isn't working, the fan should run when the compressor runs.

If the problem mostly occurs during cool weather with the top down and AC off, then the problem is the temp sensor.
