W211 AC compressor not getting amperage?
I have this '05 E320 CDI that I have been pulling my hair out trying to figure out WHY the AC compressor won't come on after I've replaced the compressor... Everything worked great until the compressor gutted itself...
I have read probably every thread y'all have related to AC issues, - checked a bazillion things, but haven't found anything that seems to be the solution to my problem - therefore the need for me to make this post...
Yes, I have the scan tool - a "Red Brick" MT2500, and a recently acquired ICarsoft MBII scanner ... so, Yes, I have reset the AC system.
My Alldata set goes up to 2006, but when they get to the "later years" MB's - their wiring diagrams are a real joke...
The problem I seem to have is the compressor only pumps by jumping power to the compressor valve - even though the plug coming to the compressor shows power with a test light, and my Fluke meter (13.6V engine running) when the AC switch is on...
What the heck am I missing?
Thanks in advance...
