OK, I need to get my A/C working again. It was working wonderfully until... One day I noticed that one of my cooling fans were not working. So I figured I would start checking the relays. The only problem was that I didn't know which relay it was. I have 4 relays (that I could find) under the hood. One on the passenger side and three on the driver's side firewall. I noticed that all of the relays are the same (I thought they were! Are they?) so I went and bought 1 relay and started swapping out the relays one by one until the fan started working again. Nothing. Anyway, one day I am driving down the street and the car almost dies on me. I shrugged it off and kept going. Then it does it again. And I start to smell smoke. Well I had to get to work, so I had to bear the smell until I got there. After getting home I found the source of the smoke. The AC controls. It seemed to be coming from the fan speed switch. So my question is... Is my switch dead? It ran for a little while when smoking. Are all the relays under the hood the same? Should I just go and replace all of them? Please help! Its hot.
