Hello all. Just bought a 1996 4x4 with SEVERAL issues. I guess I'll start a thread for each, or is it better to ask them all in one thread?

On my drive home last night with it after purchase from an individual, I noticed that the front fan only works on High, and makes a horrible noise at first.

Don't know if it matters or not, but I also don't have any heat coming from the front. Seems to be blowing out the rear controls warm, but not the front.

I read somewhere that maybe a resistor is out on the fan?

Just looking for somewhere to start the investigation. I have tools and a multimeter, just not use to Chevy's.

**Sorry, but I just realized that I posted in the wrong category. Can someone move it for me?**

Thanks.
