Hi all,
I am having a strange issue with this vehicle. It is giving approximately 52ðF at the center vent at 1500 RPM.
Given the low side, I tried adding refrigerant After adding a few ounces, the compressor would start to cycle quickly then absolutely nothing.
After evacuating a small amount, performance would return to where it was initially. It's like it just wont take anything, and the measurements tell me it needs a more
refrigerant to get the output into the low 40's.
Any help would be appreciated!
Thanks,
Matt
First things first, you have to know you have the correct charge level. Reclaim - pull a vacuum - recharge to OEM specifications. Adding a little here and removing a little there just makes a mess of things when trying to diagnose a system.

Thanks TRB. I suppose you can't always top them off.
