blower regulator
hello everyone,
my ac keeps coming on and off when ever it feels like it. from what i have read its most likely a blower regulator. if someone can help me out with a how to guide to replace it i would greatly appreciate it. i have a 2002 clk 430.
my apologies if i re-posted an old topic the only guide i found was on an older mercedes different model as well. thank you ahead of time for any assistance.

I did the reg in my 208 before. It was real easy. Just take off the cover up under the passenger side dash like you would to get to the cabin filter. Few more screws later you should have it out. For some reason I remember the blower motor coming out too. Good luck

Set a mirror on floor to help see the regulator and blower. You can remove the regulator alone (two torx screws) or the reg/blower assembly. The regulator screws are partially hidden and a bit tough to get the screws started, hence the mirror (and light). I replaced the regulator and fan still ran slow and erratic. MB mechanic said cheap regulators give a lot of problems. I bought a Behr brand regulator and it works great. Can hardly keep my toupee on now !! 
Good idea to change your cabin filter since it's right there by the blower.

I tried to locate a Behr regulator & the picture doesn't look like it's the same. What is the Behr part # and where can I find it, my blower only works when it's cool in the morning, I used to be able to thump the dash & it'd start, but now nothing. My car is black on black 2003 CLK 320 (208body) cabriolet. I'm dying in NM! HELP!

Try autohausaz.com and part number 2308210251 for your 2003. That unit looks different than the 2001 regulator. There was a model redesign in 2002 so your install steps may be different than that given in this thread. Hoepfully they are close to the same. After you change the regulator once it will seem pretty straight forward. It's tougher the first time due to unfamiliarity with reaching screws and sliding clips.

Blower Regulator out again. less than a year
Well I got the blower motor resistor changed out last year & low and behold, 11 months later it's back to it's old tricks! Is there a HEAVY DUTY regulator that will last more than 10-12 months? As I've stated before my car is triple black (Paint, top, leather!) We're only in the 90's right now, but August is coming & I'm a glow in the dark redhead so usually top down is reserved for evenings and late afternoons. I'm open to suggestions, or do I just go back to another bosche & hope this one makes a year?
