On vacation ac not working.Compressor running line into evaporator frosty just warm air.Air doors will switch between defrost cab floor ect.???

 

May have froze up......shut it off and give it 5 minutes or so.

 

It hadn't been ran befor I turned it on.

 

O.K.......can you feel any difference in air from heat to cool? I have had more than one vehicle that if it is turned from hot to cold really fast, it doesn't seem to recognize the change. Try moving the temp **** nice and slow from cold to hot, wait 30 seconds and then back to cold. Make sure that it gets hot when in the hot side too. If the line is frosty, then the a/c is capable of cooling. It sounds like there could be an issue in side. Poor airflow has been a problem when the recirc door breaks and that isn't too uncommon on you year of trucks. try that, and we'll go from there.

 

Heat control works gets real hot on heat pee warm on cold.Air flow good you can hear doors opening and closing between floor defrost recic ect.

 

Hmmm......gonna need a set of guages to hook to the a/c then. Hard to diagnose anymore without knowing some pressures. Typically , if there is enough freon to kick the compressor in and you have a line getting frosted, then there is enough freon to cool some. Which line is getting frosted? The larger diameter line, or the small one?

 

Can't remeber now the one closer to the exhaust not from the dryer.Makes no sence.I guess I will have to find a dealer when I get to myrtle beach.Probably won't be warranty under my high doller extended warranty.??

 

check you chip,,,my powermax will turn my ac off,,,take any chip or programmer of the truck and try that,,,the compressor in mine will still turn but still blows warm air until i turn the powermax and the ac fan off,,,then ill turn it back on and it blows cold,,,let me know how that works for you

 

No go I unhooked box put dummy plug in still blows pee warm.
