A/C always losses pressure
Ok people I am stumped I have 06 mega cab 5.9 and I have had nothing but problems with the a/c blowing hot. I have had the thing fixed by the dealer about 10 times and know they can't find a leak. When every I decide to take a trip from home to the mountains it seem to lose refrigerant. I live at seals so in the desert. And the highest is about 8000ft is were I go. I last filled a t in July and until the other day when I went to the mountains it was fine. Help

if they have done it that many times i would have the evaporator replaced thats the only place that is difficult to check for leaks. Have they injected DYE in the system ? if not that would be the next move. Have them inject dye and then check at night the condensate that drips out with a UV light if the water glows at night then thats your problem

Done this - get a spal slim puller fan 2" anything larger and it won't fit without bending the hood latch- fan, wiring harness, and mounting hardware can be had for $75 from Amazon. I wired this to a relay on the passenger side battery that gets its signal from the compressor- when my compressor is engaged then the fan is running- I didn't want another switch in the cab-it's not really noticeable over the fan clutch when at idle unless you are right in front of it.

I think he was referring to the entire compressor- I replaced my compressor and my new one did it a few times before adding the slim fan and new fan clutch. It has not done it since- I would try the fan and if it continues then replace the compressor at that point. During the ac repairs has the system been under vacuum all the time/done by the shop? Is your fan clutch engaging properly?
