Hello!
I've been having a issue with my blazer's A/C since I got it about 2 years ago. It simply doesn't cool most of the time, especially in summer.
This summer I went ahead to start fixing the problem.
What I've done to begin with:
- Replaced compressor with brand new ACDelco
- Replaced accumulator with brand new ACDelco
- Replaced orifice tube with brand new ACDelco
Got it filled up with gas at the shop, and it still doesn't cool as it should.
So I decided to remove the evaporator and check it, and after getting it out I found out that it was clogged from the old compressor so I gave it to the shop and they used some petrol and compressed air to get it to open, and I made them clean the condenser at the same time just in case.
After closing the dash and everything up and filling it with gas, I found out that it still doesn't cool.
Current situation is as follows, at night and early in the morning, the air is kind of warm and suddenly it starts blowing more air and start blowing ice cold air.
But any other time between early in the morning and night the A/C blows hot air, unless it decides to increase blower speed and starts blowing ice cold air.
The compressor DOES cycle on/off, goes off for ~8 seconds and then on for 1~2 seconds (not always). Even if it doesn't cycle it still blows hot air, until it decides otherwise.
I've tried to command the compressor to stay on using the Autel DS708 but again, doesn't cool.
Just to be sure, I have to fill it with 860g of gas and 220ml of oil, right? What would happen if oil was less?
Any help is appreciated.
