2000 E320 Sedan, all the AC/Heater Controls seem to work but no air flow coming out of any vents. Have seen other posts regarding replacing the Regulator but wondering how do you know/test to determine if it is the Blower Regulator or the Motor?

Thanks

i just did mine a week ago, and the DIY link is a few above your post - mine had no high air speed only slow - i bought it local 175.00 bucks and the guy tony did a good job explaining how to do it, of corse some MOPES cant follow simple directions and one even had a wire fire after doing it ( his way instead ) sooo follow the directions i crimped mine i did not solder it good luck i took me with the cabin filter change 1 hour - jz

and check if it is working with 12volts.
You can follow the diy regulator r/r on benzworld.org w210 diy section if it is the regulator.

hi there, my cluster light by A/C, Heater and others not working. do anybody knows what the cause? do i have busted lights or something...thanks yo!!!!!

Those sysmptoms are due to one or more bad lamps (backlights). If the pixels are going bad in your ODO, clock etc. then your pixels are going bad and you neede a new or refurbished cluster.

Are you referring to your "dash" (cluster) or to your CCU?

J2cruz

yep TMAllison.....i think also there is a recall on that....thanks everyone for the info...

I don't think so....but, besides going bad occassionally the CCU does have bulbs. Need radio removal tools to remove the head unit.
