My 2008 Dodge Ram 1500, this morning my A/C was working fine and blowing cold air. i later this afternoon i went to the store and when i got back in the truck the blower would not even kick on at all. i popped the hood and the evaporator was frozen over.

 

Look at THIS

Make sure you didn't pop a blower fuse. Not even sure if there is one in the TIPM module next to the battery?????

 

where would the fuse be located? do you have a pic?

 

It's the black box directly in front of the battery. Not too hard to find, just pop the hood.

 

already looked there checked both HVAC fuses they were red 10amp and the were fine. any other fuse locations? or ideas on the problem?

 

No other fuses in your truck.

I'm not an ac expert by any means so nope. Should be under warranty.

 

yea it under warranty i am taking it in the morning to be serviced, just didnt want to take it down for the day if it was an easy fix.

 

could the blower be bad?

 

Hey, sorry about your problems. I am an A/C guy. EPA certified years ago. Back in the R12 days. In not an auto A/C guy, however it sounds to me as if your running low on refrigerant. If your evaporator is freezing over, that is a tell-tell sign. A quick way to check the unit, is to turn your heater on. The heat from your heater core will melt the ice on your evaporator. If your unit is working after that, check for leaks in your system. They will look like a small oil leak. As the refrigerant moves throughout your system the compressor lubricant travels with it. The refrigerant will evaporate upon hitting the air, but the oil will condense back into a liquid. Also check for any blocks in your unit that may prevent airflow. This will cause the same condition.

 

does anyone know where the blower motor resistor is for a 2008 Ram? i checked all of the fuses in the box by the battery and they were good. whenever i turn on the AC the blower does not kick on. I was looking under the hood trying to figure out the problem and notice the evap. is frozen, whenever i turn the AC off and the evap starts to defrost. can anyone help me that has had this problem before?
