1993 mercedes 400 sel ac,climate control center not working

SOURCE: Fuel Data Center and Electronic Climate Control not funtioning

This is defenetly the BCM, I had a 1990 with all of the same problems. Buy a rebuilt and install it behind the clove box. Remember that you must install you memory prom into the new unit as they don't come with any in them (it is what is memorizing your miles driven.) You will get off pretty easy on this one as they are available and not too expensive.

SOURCE: new climate control unit but when on blower not working for heat or ac

I'm assuming the problem is the blower motor isn't coming on or working. 1st, check the fuse. 2nd, remove the glove box or pull the 2 tabs that act like stops when it's open ( the glove box will open out further) and you'll see the power plug connector for the blower unit. Turn on the blower through the climate control (heat, A/C, or whatever) and wiggle the connector to see if the blower turns on. If starts working, then an easy solution is pull the connector off and gently press the prongs together or inward. Then carefully reconnect with damaging the prongs. This worked for 96 Mark VIII due to the fact the prongs were not "seating" correctly in the female connector. It's been about 2 years since I did this and the connection is still good. If wiggling the plug doesn't work, pull the plug, turn on the climate control (heat, A/C), and check for voltage to the plug. That's about all I can help with.

SOURCE: Impala has dual climate control. AC blows cold on

with a dual climate control system, it is imperative for a proper refrigerant charge to be maintained. the symptom you describe is a possible indicator of low charge on the system. the ac evaporator core is closest to the right side of vehicle thereby making air feel cooler on that side, on the left side of the vehicle the cooled air has farther to travel and warms up from cabin air before it discharged from the vents. this is the most probable issue for your vehicle...however if the charge is accurate, the issue would be more so in the air temperature doors which is located deep inside the dash...i hope this helps...good luck!
