I have a 1999 Ford Escort LX with about 75,000 miles on it. Yesterday it stopped blowing cold air and is now blowing air like the vent was on. The air is not hot just cold. I took it to a shop and they said it was full of freon and had no leaks but that it was getting no power to the compressor relay box. Is this something I can fix and where exactly is it located at? None of the books I have looked at have a detailed diagram that shows where it is located. I really don't want to pay $300.00 that they want to charge me to fix it. Thanks for your help.
By compressor relay box, does that mean the ccrm, known as constant control relay box? How did they diagnose this? Ccrm is usually on top of the radiator, under the plastic shield. These are complicated systems, a c, and require knowledge to properly diagnose, unless it's something simple such as blown fuse, breaker, obvious broken wire, etc. I would check the above parts myself first, check all the electrical connections on the related a c parts in the engine compartment. Good luck
