92 VX wit 94 Del Slo A/C system (shouldn't matter but...)

Had the A/c on my car for over a year now always blown ICE COLD!!!!!!!! Well the wife drove it yesterday called and said it was blowing HOT AIR. I ckecked the system out its full, compresser cuts on & off like it should but it's blowing HOT. I dont get it!!!

ANY SUGGESTIONS???????????????

 

Does the condenser fan run?

Is the heater on?

What are the high and low side refrigerant pressures with the engine idling and the A/C on?

 

when you say the compressor runs, you mean the clutch is engaging?

 

Haven't heard the condenser fan cut on yet, heat is off, 35lbs on the low side, I think the clutch isnt engaging all the way....I mean it's dragging the motor down but i dont think it's not as much as it should be.

 

The condenser fan should run whenever the A/C is on. Check the relay and fuses.

 

First thing i would do is check for leaks.

Next, it sounds like you just need a recharge. because the fan wont kick on unless there is enough pressure, also i believe it wont blow cold if there is to much pressure.

 

As Ron said, the Condensor fan should run anytime the A/C is on. The only time the Condensor fan should shut off when the A/C is on is when the Thermostat(Thermistor)in the Evaporator shuts the Compressor off, The Thermostat will shut both the Compressor and Condensor fan off when the Evaporator core gets to the cutoff temp, usually 36-38 Degrees or so.

 

Well if that's the case my fan is not cutting on at all..... 100 degree weather & a 1 yr in the car is not fun!!!

 

that why you don't like the wife drive the car, they'll tear it up, but I think it's loose wire/relay/fuse.

 

car seat fits the EG better then her DC2. Thanks to all I'll try everything you said to look at.

 

Did it quit blowing cold all at once, or was it gradual?

If it was all at once, I don't necessarily think it would be low on refrigerant, because that tends to leak out over time... unless you had a catastrophic failure somewhere.

When the A/C quit all of a sudden on my 96 Accord, it ended up being the A/C compressor relay. The compressor still ran, but it didn't blow cold. Can't really tell you more on a Civic, but I think it's something like that if it just stopped.
