Ok...i have started the trouble process on the 300CE

The compressor is not engaging.

I switched out Klimas...no change.

With the engine running ...low side pressure is 100..but no compressor engaging.Last year some leaking o-rings around the expansion valve were replaced.

Sunday the A/C seemed to be working fine in 90 degree weather..maybe it could have been a bit cooler. However it was very comfortable driving.


I checked my son's 300e. Low side pressure is at 25 or so with A/C on high
His low side is at 80 with compressor off and engine running

Both cars were converted 134a.(at least by the size of the fittings)..not by my choice..that's the way they were purchased.

I really can't get anywhere with the CE until the compressor engages... the clutch turns freely by hand.

Thanks for any more ideas.

The only other unusual thing is that the car sometimes has the gurgle issue when the A/C is on and working. However, i can't seem to detect any coolant issues.


EDIT -- 8:37 pm it is dark... i'll check the ovp fuse tomorrow..but the car is running perfect otherwise. Since i have the 300e... any suggestions on switching out parts helps me..
