My wife's 2006 CLK 350 Cabriolet has 22,000 miles on it and has had an A/C issue for awhile now. Whenever we turn on the ac, after about 5 mintues (and it's a random timie) the blower motor turns off. Then a short time later (2-5 minutes) it will just come back on. THe air is still cold and I can smell the freon/compressor in the air for the first few seconds it's back on, so I know it's not the compressor. It's a fan.
Anyone heard of this before? Suggestions? Thanks!

It could be a defective blower motor or its "regulator". These are easily accessed by removing the paneling under the dash in the passenger side footwell.

Thanks, I'll try this. Is it possible it's a bad relay?

Rudeney

I don't believe there is a relay for the ACC fan motor - just fuse #51 on the front SAM.

I have exactly same problem...can you please share with us if and how did you fix that problem!? Thanks.

My wife's CLK350 had this problem. I have replaced the blower motor and so far, so good. The regulator Rodney refers to is sold as a separate part, the old one has to be transferred to the new blower motor assembly if you will be re-using it. Fingers crossed that this part is not the actual problem...

Thank you

Hello,

I had the same exact problem and changing the blower regulator fixed it. Was about 185 dollars.

Thanks

sadovak

no luck for my guys. I replaced blower motor and regulator but problem still persist
I did a/c test-reset but this time the lights never stop "blinking"

any idea? thanks

pskdude

Damn, not good. I can only imagine it would be your a/c Cluster at this point.

The lights not stopping the blinking are because a flap actuator or lever arent working properly. Ive been trying to diagnose myself but will be taking it in to someone with SDS to see what error codes i pull...

update: guys, in my case it was light/sun sensor it's located at engine hood grill. it cost me $330 total

pskdude

wow. how awkward that would affect your a/c ?
