1999 Suburban….A/C Compressor question
I recently purchased a 1999 Chevy Suburban 1500, auto tranny, 350 engine. I was told the AC wasnt working, and that the ladies mechanic quoted 800 dollars to fix the compressor. The vehicle has dual AC, front and rear. The blower on the front turns on and off when it feels like it, but the blower on the rear AC works fine.
I bought a remanufactured compressor and installed it myself. The system was empty of freon, so I bought 4 15 oz. cans of r134A and put them into the low line. As I finished each can, I held my hand in front of the rear A/C vents (the vehicle was running the whole time I was putting the refridgerant in) and it got a little cooler each time.
By the time all 4 cans were in, the air was cool, but not cold, and nowhere near cold. I beleive the freon capacity for this vehicle to be 64 oz, so the 60 oz I put in should suffice. Does it take awhile to run through the system? Should I add more freon? I just finished a second ago. I only let it run for 5 minutes after i was finished, and it didnt seem to get getting any colder.
Also, I am no mechanic, so I could have made some sort of mistake during all this.
Not necessarily true…….
Since the system was not evacuated prior to charging, it was full of “AIR”……..60 oz of freon + 64 oz of air makes for an extremely unstable environment, so dont expect much better than what you have.
