Hey guys have an 03 ram 1500 slt 4x4
With In the past year I've replaced in regards to a/c: compressor, drier, resistor, blower motor.
Everything has been great till yesterday it all of sudden stopped blowing cold and blows WARM... Checked freon levels and there perfect. No weird noises or anything noticeably different. I'm baffled! Any help would be great guys!

 

Is it just blowing cold air if moving? Warm at idle? Check you condenser fan.

 

Condenser fan should be running strongly, all the time the AC is on.
Al

 

do you smell coolant out of the vents at all?

 

It will blow hot air thru vents while a/c Is off. The condenser fan is not kicking on at all.

 

Turn on your ac then check the voltage at the fan? No voltage then it's not the fan. If there is voltage, then fan is out.

 

Alright y'all, installed new fan and motor assembly. Now it blows hard out and cold of drivers side vents but weak and warm on passengers! Ugh! Just can't win!

 

Any ideas as to why it's blowing cold out of only the drivers side? Blower motor and resister are perfect shape...

 

Sounds like your blend doors. Maybe one broken. Common issue.
