The a/c worked fine yesterday ,today it blows hot air. Wont take any 134,when I attach the re-charge hose it shows 150 lbs. Then I go to turn on the a/c and the screen is all lit up but I have nothing working,no fan,temp,nothing... Any help ?

 

Before you started trying to recharge it was the blend door checked for correct operation?

 

Thanks for the reply ! No,I just assumed refrig. was low. Like I said,it all worked fine the day before,then nothing. Compressor doesn't come on . Now the the nscreen shows all lights,def,fan,heat,etc... but nothing works at all

 

how do I check the door ?

 

Might have a problem there......if all the lights are lit up ........

Check the fuses and connections....

Also try taking the eatc /climate controller and unplugging it and plug it back in.....see if that resets it.

 

I replaced the relays first,then my wife had the truck for 4 days,it reset itself ! Everything back to normal ! Weird
