What's up everyone?
I have a 97 XLT with the 5.4. Driving the other day, I switched on the panel vent to cold, and all that came out of the vent was hot air. I then switched on the A/C to normal and then to max settings and got the same result, HOT air. I thought that I may just need an A/C recharge since it hadn't been run since the fall, but then I noticed other problems.
1. No cruise control
2. No reverse lights
I checked my Haynes repair manual and the factory manual, did some investigating, and found a 15 amp fuse blown that controls the A/C clutch, hybrid fan relay, speed control, DRL (whatever that stands for), panel blend door actuator, and EVO steering module.
After replacing the fuse many times, and through process of elimination, I finally disconnected the electrical connector at the compressor clutch cycling switch under the hood on top of the accumulator/dryer and the fuse did not blow. Reverse lights back working, and cruise control back working but no A/C.
Sorry for the long explination, but the more info the better I guess. Has anyone else had similar issues and what was the solution?
I'm going to replace the clutch cycling switch today, only $10, but if that doesn't fix it, then I think my next step would be the compressor clutch.
Any input would be great. Thanks.
Ok, so I replaced the clutch cycling switch. No change. Still blows the fuse as soon as I switch on the A/C. I think the next step is to replace either the A/C clutch itself. Anyone's input would be greatly appreciated. Thanks again.
