I have a 96 *-10 4x4 and have been experiencing intermittent blowing from my vents, when it does work it blows cold air. Sometimes when I crank my truck it works but most of the time it will not blow any air. After doing some research I have it narrowed down to the resistor or blower motor. I am not the most auto knowledgeable guy but it seems like this is something I could replace myself. Any advice, tips, pictures or videos would be greatly appreciated. I have to fix this soon it is 100+ degrees down here in Georgia.

Thanks.

Check all your fuses first.

I checked all the fuses and replaced the resistor, I have cranked it a couple different times and each time it has been blowing cold air but I guess only time will truly tell. It still doesn't want to blow when on Max A/C and on high though which worries me.

high is usually a different fuse and a different circuit.
