A/C Doesn't blow at all, but works fine at times?
Hey guys, wondering if you could help me out? My A/C doesn't blow ANY air about 95% of the time...but every once in a while, I get in the car and it's working like normal. Blows hard, cool air. I'm assuming this is the relay? The recall has already been done on my car, so I don't think Mercedes replaces it again correct? Or could it be my blower motor is just pretty much dead? Also if anyone can give me detailed instructions, or a picture of where the blower motor is that would be great, i've been looking behind the glovebox but I haven't seen 4 screws anywere. Thanks in advance!

It is probably a failed blower control unit. See https://mbworld.org/forums/s-class-w...blem-help.html and https://mbworld.org/forums/s-class-w...regulator.html
You can order the blower control unit separately from the blower, and save a lot of $$. Be sure to order the one for your car (posting the model year and your location - at least the continent you live on - is helpful to us in answering).

it is accessible from the underneath the glove box in the panel that lays flat up against the bottom of the dash more toward your knees. Get under there and look up. Dont quite remember what screw configuration but remember the glove box did not come out and was not removed.
