Early W210 Blower Motor Regulator Replacement DIY Here...
#251
Mine works all summer then when it gets cold it doesn't work or works sometimes. I have a 2000 E430. Ordered a new regulator (new version). Put it in today and it didn't work. Unplugged it plugged it back in and it worked. Then the climate control wouldn't turn it down from full blast. Kept doing this for a while. I would work with the controls sometimes then it wouldn't. I gave up and came in and read this forum for a while. Thought it might be the Climate control unit itself. I was one click away from buying one and I figured I should pull the old one first. Then i figured I might as well put the old regulator back in with the blower motor seeing as that probably wasn't it. So I did and now I get nothing at all. So I go to touch the red wire where it goes into the motor itself and it comes on. So I try the CC controls and everything is working normal. I figured I found the loose wire maybe I can solder it etc. So I try bending the two wires where they go into the motor every which way in order to make it stutter or stop but nothing. It just work all the time now. I figure I found a loose wire. It's been working perfectly since. I may also have brushes that are going. If it stops again I'll replace the motor. So if you have erratic operation it could be the motor not the climate control unit. Basically this was a very long way of saying I found a loose wire on the motor and I couldn't be happier.

2001 clk320
I replaced the regulator in my CLK320 and it did not fix the problem so I replaced the fan/motor assembly. Still not working right. A MB mechanic told me there are a lot of problems with cheap replacement regulators. I bought a Behr regulator (from autohausAZ) and now it blows my toupee off.

Rookie needs help
New to the forum. Here is where I am...
1996 E300D, 175K
AC blower stopped. Found this thread and ordered the W124 regulator from deutschepartsusa
Plugged and played without cutting and splicing to be sure regulator would solve the problem.
Turned on climate control.... JOY TO THE WORLD !!!! the blower works.
Everything is working fine and I am feeling very proud.
Went for a ride and fan stopped. After a mild stroke, I parked it for the night to let my BP settle.
Next morning, climate control works... for a while... then it stops again.
Stroke a little stronger this time.
Fast forward through a couple of more cycles of this... and here I am.
I have 12v to the red and blue wires to the motor with fan control on max.
Took the fan and hot wired it to 12 volt battery. She runs. Plug everything back up and BINGO... no voltage to motor. Unhook motor and I show 12v on the red and blue again.
Help?

Regulator replaced
Had the problem about 2 years ago on a 96 E320. Got the S140 regulator for about $37.00 at WWW.thepartsbin.com
Used wire splices and all works well still.

If you look around you should be able to find one that doesn't require splicing. Bought mine on ebay for $59 and it already had the wiring in place and was a simple drop-in replacement. Took about 5 minutes to replace once I had the blower out, total job was less than 30 minutes.

Brilliant! I'm slow (hampered by seat that won't adjust back - and it only took about two hours to complete this project - cost for the part was 25 on eBay. I couldn't wait on a USA part as I go on vacation in two days - driving! Anyway, again, Brilliant!

have a 98 E320 that the blower fan has quit - is there a part that we can order that does not require the splicing of the wires? Know that we have an early W210, and that we need the W140 from the S class.

Hey all,
My 2002 A/C was blowing very weak so I ordered the blower regulator Had that replaced and it worked for a bit. After a month or so, I turn on the A/C again. Nothing come out at all! I checked the fuse and they look good. Do you think it's because the new regulator is not compatible with the blower motor or the motor is just bad? Anyway to check this? Thanks in advance!

Great instructions
I just changed the blower motor and regulator using this thread. What a help! I also change all the cabin filters. I found that Importec had the parts cheaper than anyplace else when getting a non-oem blower motor. The part works great and we saved over $800 from what the dealer wanted to charge to replace everything.

Perfect fix!!
I followed the post and installed the W140 regulator in me '98 e320 wagon, and it worked perfectly!!
Hopefully I'll get another 157000 miles out of it!! 19.95 free ship off of ebay. It's worked for a month, no problems...
