Crazy AC Problem, please help!

[dleopard19]

ok when i first start my day and get into my truck my ac blows ice and when my truck gets to normal operating temps, which is like 15 minutes it immediately begins to sweat me out of the truck. It's full of freon and my compressor runs like a champ, it just decides to blow hot after its warmed up, anyone have any ideas, its 100 degrees everyday in memphis and my ole lady hates my truck right now

sounds like a pressure switch to me

[dleopard19]

what kind of pressure switch?

[dereku]

isnt there a valve that lets the coolant into the heater core maybe thats bad. it is probably what a pressure switch is I just don't know so theres my 2 cents.

Kind of have the same problem. When im idling at a stop, my truck starts to blow warm air, but when i get moving again the air gets cold again. Anybody know what might be going on?

Check your drain tube. If it's plugged the condensation can't escape and will actually freeze around the evaperator... blower can't push air thru a block of ice!

Mine does that too. I figured that was due to the difference in the amount of air flowing thru the condenser. Might help if you checked to see how many fins are damaged on the condenser... Or maybe there's alot of bugs in it?

check and make sure u have proper air flow across the condenser devious i notice u have 4 beautiful off road lights in front of your grill.

Sounds like a blend door issue to me. Clamp off your heater hoses and drive it around like that and see if it stops.
