| Posted: Wed Jul 09, 2008 8:21 pm Post subject: A/C Compressor clutch will not engage |
|
|
I just retro-fitted and re-charged my system with Arctic Freeze 134a+
Almost everything is in working order;
The compressor spins and isn't seized.
The new coolant is holding, and not leaking.
HOWEVER!
When I turn on the A/C, the electromagnetic clutch to turn the compressor will not engage.
I tested (and recharged the system) by running 12 volts to the clutch off the battery. That works, and engages the clutch, however it blows the 25 amp A/C fuse, and thus kills the fan to blow the cool air inside the car.
If I take the A/C Fuse out, run the clutch directly off the battery for about a minute, disconnect the clutch and quickly replace the fuse, it blows really cold 'it definitely is working' air.
But then it warms up again because the compressor clutch isn't engaged.
Long story short
My electromagnetic A/C clutch will not engage, and the system is at full (recommended) pressure.
What do I do? |

Nevermind this, I dropped it off at a GM dealer this morning about half an hour ago.
Edit;
Holy shit this turned out expensive. $580 for everything, and that's with them not adding any more refrigerant! I already dropped $120 on the refrigerant and retrofit kits. $700 investment...
Cold air is expensive.
Confirmed to be the pressure safety cutout switch, I'll have it back in two or so hours.
They also fixed my driver side window! :D :D :D :D :D :D
It doesn't rattle in the door anymore, so I can close the door without fear of breaking the window. Awesome. |
