Brand New Condenser and Compressor and 2005 Mazda 3 blowing hot air. Why?
I have a 2005 Mazda 3. The AC is not blowing cold air at all. So initially I
figured there was a leak somewhere on the system. I used UV Dye and found
out that the condenser was leaking out the freon. I bought a new condenser
replaced the old one to find out that the "new" condenser was faulty (leaking
out the freon).
Now I returned that condenser and changed it yet again when putting the freon
in it is not blowing cold air. Decided to take it into a shop. The mechanic there
said that the compressor was bad. So I went ahead and purchased a brand
new AC compressor. The mechanic changed it car still not blowing cold air.
When looking for leaks there are none that is visible. The mechanic at the shop
said the high side is holding the pressure but the low side is not holding the
pressure, but it keeps taking in the freon but no visible leaks. He has no clue
what is happening.
Any ideas as to why the AC is not blowing cold air with a brand new
condenser and compressor ?
Did they change the high and low pressure switches?All so did they vacume the system before charging it?
They did not change the high and low pressure switches. But they did vacuum the system before charging it. Could it be the high and low pressure switches ?
Yes,if one or both are bad,it will cause the freon to blow out,they control the cycling of the compressor,and if bad will continue to run and biuld to much pressure,this may be why you cant find leak,it blows it out all at once,out the pressure release valve on compressor.
Changing all those parts did they change the orifice tube filter or expansion valve depending on which one your A.C system has.
What I can't wrap my head around though. When i changed the condenser the first time. The AC was blowing extremely cold air, it worked for about 3-4 days until I realized that new condenser some how had a leak. That's when i returned it and changed it and this time the compressor too and is not blowing cold air. But i will have the mechanic check the high and low pressure switches! Thank you for taking time to read and answer my question!
@ firebird338 The only thing they changed was the compressor. The mechanic took it out and replaced it with the new one. After which he pulled a vacuum and and put back in freon. Is the leak possibly at the expansion valve?
