I'd guess a simple AC recharge!

 

Also If your pulling a load or accelerating your ac might kick off.

 

Sorry not trying to high jack this thread but I did a search and this thread came up and maybe it will help all of us.

Im having the same issue. sometimes I turn the blower switch off then turn it back on. it starts blowing cold again but usually after a few minutes it starts blowing warm again. Could this be that door issue. and also one of the condensor lines will get so hot it will burn you, is this right.

Im trying to wire up a auxillary fan to see if it will help. having problems with wiring it up. anyone have a diagram with the factory wiring colors?

 

Did this to mine and it made a big difference
