I have a late 1989 pickup ext cb 4x4 . Recently I was driving, left for a little bit came back and my a/c was not blowing at all. I've checked all my fuses and there all okay I couldn't figure out which ones were the blower fuses though. Any ideas on what it might be I'm stuck? I really need to figure it out soon this summer heat is killing me. Thanks in advance!

So is the blower motor working?

 

It was before I'm not sure now it's not blowing at all

 

Is the ac compressor kicking on at all? If your blower motor fuse is good you might have to test it at the blower motor behind the glove to see if its getting power, I don't think it's to hard to replace if that's the case but I would double, double check your fuses. I would even pull the fuse and replace just for fun I have had fuses that look fine and still don't work

You also have a blower motor resistor that could go bad also but usually it will just not work all the fan speeds not completely stop working but it's possible.

 

No I don't think so like I said its not working at all. And how would I check it?

 

Ok having a hard time here, is your fan blowing hot air or nothing? Like when you turn your fan on high does it do anything. And you can hear your compressor turn on if you turn your ac on and you can also look to see if its spinning at the compressor itself under the hood.

 

No not hot air not even on high and no I can't hear it do anything when I turn it on

I took a look at the diagram but it's leading me to the relay ,blower motor and blower resistor where can I find the a/c and heater fuses to check those?

 

They are behind the glove box. I had to remove my whole glove box to get to them on one year mod they on the right side of glove box with box out and on my 88 they are on the left side of glovebox with box out.think the ten amp is a/c and the twenty amp is heater blower motor fuses the relays are located next to the fuses.

if it gets low of freeon the compressor wont kick in. just add a can of freeon it should start working.i always unhook the plug in connecter on the compressor and put a jumper in it so the compressor runs it will suck the freeon in faster that way plus if it doesnt run with the jumper wire then its a bad compressor
