i replaced clutch & pulley. now comppresser won.t kick in. message: low freon, compresser off. is there a relay or fuse?

RE: air conditioner

Erase all A/C related codes. Assuming its full of freon, it should engage. I believe it says how to service the system on the yellow underhood decal.

RE: air conditioner

thanks carnut, how do i erase codes?

RE: air conditioner

Just disconnect and reconnect the ground on the battery.

OR you can do it from the climate control panel.

IF it is like mine it would go like this:

You push OFF and WARMER at the same time. and then where the fuel data is display it will flash codes. when it stops and says .7.0 then press OFF and LO at the same time and it should then display F.O.0 which clears the BCM codes. Then hit OFF and HI at the same time and it should show E.O.0. (clears ECM codes) and then in a few seconds should switch back to .7.0
