Ok I bought my truck last year. When I bought it the AC didn't work,well they fixed it before I bought it. Well about six months after I bought it it went out again. I smelled what I would say like burnt wire smell. Since then I have had no AC. I looked under the hood and see the condenser fan running fine to me. I'm not sure I hear the condenser turning on though. I looked at the fuses but I'm not sure what one goes to the Condenser fan motor or whatever part runs the AC. I'm not sure if there is a leak of the AC coolant. How would I know if that's the case please any help would be greatful.
