I have a 2001 Dodge Grand Caravan. I have replaced the compressor, dryer, oriface, blower resister motor and the cabin air filter. Everything is working great except it is still not cooling. I had the refrigerant refilled last month. The pressure guage shows it is full. Can someone point me in another direction to solve this issue?

 

Full or not there could be any number of things wrong.

You need to put some gauges on the system and see what it's doing.
It could be working and and an air valve or some other thing can be wrong.

A set of gauges is pretty cheap at someplace like harbor freight.

Is the compressor running?

Yes it is.

 

When you had the system open did you evacuate the system with a vacuum pump before filling it with freon?

 

Sorry for the delay in answering. I took the van to the shop and the tech evacuated the system and removed 2.55 lbs. He replace a cap and refilled the system with refrigerant and dye to see if it was leaking. I have had cold air for almost a week and even on my way to work this morning, it was cold. However, when I went to lunch a hour ago, it is not cold at all. However, I was almost back to my office, when it started blowing just barely cool air. I made an appointment for them to look at it again in the morning. To my way of thinking, if they evacuated so much refrigerant AND since it was cold this morning, I don't think it is a leak. I am thinking it is something else. Thoughts? Or am I missing something?

 

Could be low or high pressure switch is no good, could be the blend door is not opening to let cold air into the cabin.

Could be too much oil is sitting in the evaporator core??

Could still be a leak.

Have it checked.
