I just finished pulling everything apart. The evaporator box was full of leaves and crap. I probably removed about 3 to 4 cups of material. The resistor also had some fried bugs and other stuff lodged in it. The blower fan had some leaves in it too but not as bad. I sprayed everything down with electronics cleaner and re-assembled. Everything works fine now! The fan runs on all 3 speeds and auto. The whole thing took about 30 minutes. Thanks a lot everyone for the guidance. No more sweating in my car!

Thanks. That is what I thought based on my search.

I have searched this topic and I think I have my answer but would like opinions to be certain. Since I got my 93 the a/c fan has been sketchy. Works sometimes but not others. When it would not work on its own I could tap the area under the glove box and it would start up. As of this morning that trick doesn't work anymore. Does that sound like the resistor? The other posts I read referred to the switch only working in one position. That is not exactly my situation. I just want to make sure I am looking at the right fix. Thanks

Thanks everyone for all of the advice. This seems to be a great forum with good folks on it! I look forward to posting some more as things arise.

Ok that makes sense. Thanks for the education.

Thanks for the quick reply. How does the E-AT differ from the overdrive button? Seems like they do the same thing? (Please excuse my ignorance, I have never had a truck with either switch.)

Greetings, I just bought a 1993 with no owners manual. What is the E-AT switch on the dash? And how do you use it? Also, I have noticed that mine sits a little lower in the back than it does in the front. Is this an indication of a crapped out rear suspension? Lastly, what viscosity oil should I be running? I live in NC so temperature is moderate and I do a mix of short drives and some longer commutes. Thanks Mike
