Does anybody know where the a/c compressor relay is located on a 87 cherokee straight 6.

 

it is on the right fender well,there is 4 square relays,it is the first one from the front,if you still have the cover over them you will need to remove it to get to them

 

Well I guess its not my relay. Not the fuse either. What else could it be? Is there any way to jump the compressor to see if it engages? I have two wires running into one.

 

Turn on your a/c and see if you have power at the comp,it is the single wire,if it does then jumper the low cutout switch,they are both in the same area and see if it starts.

 

After you jump in and find out it works, you will probably find it is low on refrigerant. The low pressure safety switch prevents it from engaging when low.

 

Well for some reason it works now but now I have no air blowing through my vents.

 

did it just start working or did you make it work?as far as the vents you must have a vacuum line off or you selected normal cooling.

 

It just started working.

 

something you pulled or unplugged caused it,makes notes for the future.

 

everything I unplugged got immediatly got plugged back in after checking it.

 

Something you did brought it back to life,sometimes strange things just happen.

 

But what about it not blowing any air?

 

no air throuh your vents you mean the front registers?if that is the case you have an actuator problem either it is broken or there is no vacuum to it,you can here the actuators when you switch them,you may have to pull the climate controller to see what is wrong.

 

So what I am looking for on the contoller?

 

you have to pull it from the dash and see if all is hooked up,you should be able to here the doors opening and closing as you move the levers.
