Lately my A/C has been acting up so any help would be great.
When I let the truck idle with the A/C on for about 10-15 minutes I start to get a "burnt electrical" smell and a couple minutes later it starts blowing hot air. If I'm driving normally, it won't kick out.
It first did this a few weeks ago when I ran into Home Depot and my wife stayed in the truck. As soon as I smelled it, I shut off the truck and popped the hood. I saw what looked like smoke coming from the front of the compressor area. I figured that maybe the A/C clutch was wearing out (happened to me on another car), but wasn't sure. Another mechanic told be that the high pressure side could be building up too much pressure because it wasn't getting cooled down properly and to check to see if there was an auxillary fan that crapped out. I didn't find any aux fans in the engine compartment.
I know I need to check the refrigerant pressure, but since the A/C runs fine while I'm driving I really don't think that's it. I don't know what else to look for as A/C systems are an area I need to learn a lot more about. I guess now is the time. LOL. Getting my hands dirty is not a problem either.
Anyone have any other ideas what to do/look for before I have to take it in? I have an '01 Job2 with 174K miles on it.
Thanks, Doug
