dbritey 07-22-2009, 03:48 PM A/C on the car does not work. Code from dash (09) low freon. Filled Freon but compressor clutch does not engage. When you hot wire the clutch and disconnect the plug, do you just run the hot wiire to one prong of the plug, or do you have to run a hot to one and a ground to the other? I want to see if the compressor is good. Thanks 95vette 07-22-2009, 04:43 PM A/C on the car does not work. Code from dash (09) low freon. Filled Freon but compressor clutch does not engage.

Thanks You should be able to just jump the pressure switch to get power to the clutch if it is sensing a hi or lo freon charge. ps- You can't fill an AC system if the compressor is not working. dbritey 07-22-2009, 05:24 PM Where is the pressure switch located ? thanks for your help:thumbsup: toobroketoretire 07-22-2009, 06:09 PM How did you charge your A/C if your clutch doesn't engage? vetteoz 07-26-2009, 09:14 PM When you hot wire the clutch and disconnect the plug, do you just run the hot wiire to one prong of the plug, or do you have to run a hot to one and a ground to the other? As the plug has two pins I would say you need 12V and a ground to pull clutch in toobroketoretire 07-27-2009, 10:46 AM You make up a 4" long jumper wire with a 1/4" male spade terminal on each end. Then you plug each end of that jumper wire into your A/C plug. That sends current to your A/C clutch and energizes it. Simple as that............ dbritey 08-01-2009, 07:12 PM Got to working on my car today. Disconnected the battery to erase code , jumped low pressure switch. clutch engaged and was able to charge system. Thanks for all your help.:beerbang: :sm_party: SportsCarsUnlimited 08-05-2009, 12:34 AM If the A/C panel light is blinking, Before adding freon you must unhook the battery to clear the codes,Then Recharge the A/C and everything will work as new.
