I had posted this issue some time ago, thought i had corrected the issue, but apparently only made a very very slight improvement. Issue is low air flow with the climate control system. I now need to use a/c again and any suggestions would be great. Air flow does change with low, auto, and high settings, but not even close in comparison to a 95 e320 climate control system i tried out. Don't know if related to the issue, but i think the air flow is making more noise in the car that it should be making. Pulled the passenger airbag (to test the vacuum pods of the climate control system) and tested each port on the 7-port manifold with a mityvac. All hold vacuum well and with car idling, the supply line from the engine to this manifold has about 16 HG of vacuum. Later, i unplugged the supply line to this manifold, turned on a/c and barely noticeable air was coming out of the system. I read some other posts where if vacuum was issue air goes to defroster. Not the case here as with all push button settings there is weak air flow. I believe blower motor is the incorrect one installed by the PO, unless low or no freon in the system would cause weak air flow. It may be that the blower motor currently installed in my car is for older a/c w124 systems which did not have cabin filters like my car has and which I changed about 1 year ago. I would think freon level would not be tied to air flow amount, but i may be wrong. A/c setting air stays warm causing me to look at freon level being involved. The action from my last post for this issue that made a slight improvement, was removing the squirrel cages off the blower motor, flipping them around, and re-installing them onto blower motor again. Thanx for taking the time to read this and sorry for the long post.
