Bernd, I would swing by but i wont be headed to Ausitn any time soon.
Do y'all replace the filter dryer when the system is open to the air?
In home apps we allways replace the dryer any time the system is open.
I figured if the fan wasn't drawing enough air across the radiator\Condensor
that the A/C
wouldn't work.
Are you and Tom coming out to the Houston Mopar Show and Race this year?
