I took the existing cooling fan relay apart.check the contacts .reinstalled it.and the fan wasn't cooling after I turn the car off running hot.hopefull thinking I bought a new relay.and the problem was the same, stayed on forever and drained the battery.
Regards first Porsche.
I had a new battery installed on the 944s porsche and a week later I needed a jump start because the battery drained.
I have guages and am mechanical inclined, do I need to evacuate the system or can I add the 134a with the R12?
