2002 E430 Sprt/w W211 wheels
Hello guys, I knew that my new(to me) E430 needed A/C recharge as I was told by the PO, lately I am trying to figure out what exactly is wrong with it before buying refrigerant and trying to recharge the system. So I know how much we value the sensor readings and "CODES", so here it goes, my #7 on the climate control always reads 01 no matter the situation, on a cold night, broad daylight, car sitting, running in hot or cold, it's always at 01 and the only code I have is 1416 which is the REST function even though it seems to work, I don't even get the B1241 which is for low refrigerant. But my compressor never comes on because the pressure never increases even when the EC light is off, on my old E430, it even went to 00 at times but when I turned the AC on, it went up quickly and cooled the cabin, but on this one at least if it were to kick in the pressure would go up and give me some cooling even if it was a bit low. So how do I try to get the compressor to come on so I can see how much the #7 value increases assuming it is not completely bad. I am able to spin the outer part of the pulley freely so it's not jammed or anything.
