A/C-defrost disable for the winter

Hey all. Looking for a solution. My A/C clutch disintegrated this summer. I am looking to fix in the spring. In the meantime I need to run my defrost this winter. I'm looking for the best way to disable the A/C so that when I switch to defrost on the rotary dial, the A/C will not try to run. TIA Cheers, Dave

 

Just pull the MG CLT Relay in the engine bay fuse box, that will prevent it from sending power to the A/C clutch.
Note your A/C light may flash if it tries to engage it but it won't power up the clutch with the relay removed.

 

Wicked awesome, thanks!

 

That part worked good. Light still flashes, but I can live with that. Next question. I hooked up my old school aftermarket A/C recharge kit with a gauge to the low pressure port. 0 psi. Can I assume when the A/C clutch went it took out the front seal of the compressor? Won't get done til the spring. Thought I might get away with just replacing the clutch.

 

is this full time or only during defrost

 

Certainly plausible, unless you can obviously see oil around A/C components you would need to use other methods to find the leak like pressurizing the system and using a leak detector to find the leak.

Removing the MG CLT relay would disable any compressor operation.

If your looking to keep the A/C from coming on in defrost mode but keeping all other functionality there's a mod for that, on 05-08 it's as simple as sniping a wire. 09-15 you have to tie the wire to 12v.

If I understand your question, it's full time delete as I don't need my A/C til spring, but need to run the defrost without the clutch trying to engage

 

If there's no charge in the system, you're going to need a new dryer as well.

 

I will leak test in the spring to determine if the clutch chunks may have taken n out the compressor seal and go from there.

 

Party on. I can see I'm gonna have to blow the dust off my wallet in the spring ;-)

 

so apparently there is a wire mod someone posted (thank you) for disabling compressor during defrost.

full time complete disable is probably not a good idea. Versus getting it moving and working sometimes and circulating the oil and gas.

 

Complete disable is a great idea when the A/C clutch is pooched hard and there is no more oil and gas to circulate ;-)
