A/C issue on a 91 B2200
Hi, I have a 91 B2200 carbureted. I bought it recently and notice that the fan blower will only work on the highest setting. Whenever I turn on the A/C, it will not blow cold air when I turn the fan on (position 4). However, if I turn the fan to position 1-3, I will hear the compressor kick on and the idle will drop. If I move it back to 4, the fan will be blowing cold air for about 45 seconds. Basically, what I have to do is flip the fan switch back & forth to manually cycle the compressor. I believe this problem might be linked to the fan speed resistor. I have found those on ebaymotors, however, where is it located, and how hard is it to get to? If replacing that doesn't solve the problem, how can I get the A/C to function correctly? Any help is appreciated.
