2002 ML320 A/C problems
Trying to help out a co-worker with his 02 ML320.
A/C system is not working, system has had it's refrigerant recovered, system was vacuumed and recharged with 750g of R134a.
Only seeing 5v DC to the compressor. Is that correct and the problem likely lies with the compressor or incorrect and the problem is elsewhere?
I've read elsewhere that 5v DC should be the expected voltage at the pressure switch (which it is), I'm just wondering if that same voltage is used at the compressor itself or should it be 12v DC?
Thanks in advance!
