What happens if you turn on AC without Freon?
Although an air conditioner can still function at lessened cooling power after it loses refrigerant, it will start to sustain serious damage that will eventually lead to larger repair needs and possibly a full system breakdown. Loss of refrigerant will also threaten to damage the compressor, leading to it overheating.
Why is my AC not cooling but Freon full and compressor working?
Ooops – if low it could drop instead – thanks for the catch. I think that’s just a static pressure that we are seeing for now. However, since this seems to cool just the slightest bit suggests a low charge which for a 2008 is a bit rare but a stone can hit the condenser on your way home with a new car??
What kind of refrigerant does a 2000 Chevy Silverado use?
Note: a U.S. built 2000 model year truck uses R134a refrigerant, not Freon (R12). OK, you’re on the right track. If the system is fully charged (pressure correct), but the A/C compressor clutch does not engage, the fault is electrical.
What to do if your car AC won’t take Freon?
If your car AC won’t take Freon, you can check the compressor, use a manifold gauge set, and pick up a recharging kit.
Why is my a / C compressor not engaging in my Chevy Silverado?
RE: Terry, If you have power on 86 and 85 is a confirmed good ground from the PCM and you jumped 30 to 87 and the compressor clutch engages then it is possible the relay is faulty. To check the relay, put 12 volts on 86 and ground 85 then use an ohm meter and check the continuity at 30 and 87.
