Any tips would be great thanks.How to get my air conditioning clutch to engage?Did you plug the electrical connector back on the compressor? When it's cold outside usually the a/c clutch will not even engage. (I think if it's below 35 degrees). You can also warm the engine up good so the temperature will rise in the engine compartment. Also there is a pressure switch/sensor on one of the lines going to it, you may have to add some refrigerant first before it will start working. Don't forget to check for blown fuses.How to get my air conditioning clutch to engage?did you adjust or use feeler gage for the gap on the clutchHow to get my air conditioning clutch to engage?May be adding refrigerant and oil will helpHow to get my air conditioning clutch to engage?check refr. first. here is the capacity. anything less or more can impact the clutch.

good luck.How to get my air conditioning clutch to engage?Is the compressor and clutch you have installed is a new one on your 1999 Oldsmobile Bravada? If yes, there should be no problem at all, except you miss connecting the cable. The compressor clutch is engaging by magnet, and the magnet got power by electric. If the clutch doenst has power, the magnetic won't work, and by that the clutch won't engage. If use install a used parts, please check the washer in use to install the clutch. A thick gap can make the clutch always engaging. A wide gap will make magnet can hold the clutch to engaging and get work. Beside the wire of the clutch, don't forget to check the fuse.How to get my air conditioning clutch to engage?you are low on freon. it won't engage unless you add some more.
