I sent my '99 E300 Turbodiesel to a shop that a guy named "Joe Cool" works. He is an AC specialist. He worked previously with his father in a shop that did nothing but AC work.
I dropped the car off 5 days ago. The manager told me that the blower motor and blower motor regulator needs replacement at a cost of $ 907. After these parts are installed, they could look for other problems.
I really don't have that kind of money laying around, so if anyone can help this slightly disabled Navy vet, with a good set of hands, I would be much abliged.

i definitely cant help but what were the probs originally ?? i have a 00 320 and the blower is extremely poor and not much heat even when engine is hot.. even heat regulator doesnt determine what heat it will emit..

It is an easy do-it-your-self project. I just changed my blower and regulator. All you have to do is remove the screws (I think there are 3) to remove the trim under the glove box area. At this point you will see blower cover. Again all you have to do is remove a few screws and the cover comes off and the blower is right there. Very easy too do.. You can buy a new blower for $97 from Go-Parts.com and a resistor for $91 fron AutohausAz delivered. The blower has a lifetime warranty. I will post the links for you below. Good luck!!

This is my FIRST post here at MBWorld, and I have a problem -

I have a 1999 W210 - E430 and the A/C fan is a psyho as Sybil.... it runs when it wants to and shuts down anytime, leaving us with NO FAN activity whatsoever.

Now I know what some are going to already say - "Oh you just HAVE to do that DIY fix using the S-Class Blower Motor Regulator, and swap out the E-Class for the S-class...

This - I do not think I can do - due to compatibility of the parts, as my E430 was built in October of 1998. It's a pre-facelift E class with a fan unit that has a PLASTIC frame instead of the cast aluminum one



THIS is the Blower Motor Regulator THAT I HAVE:





I ordered this S-Class Blower Motor Regulator that was listed in the DIY Instructions Thread:

front


back


This S-Class part clearly does not match up with the fan and regulator assembly that I have, so anyone have any suggestions?

The only other thing I can think of - is to replace the CCU, as the digital screen shows that the letter or number FARTHEST TO THE RIGHT IN THE DISPLAY DOES NOT SHOW TOTALLY - when it is supposed to show "FF" - instead it looks an "F with a "backwards 7 to the right of the first "F" (reading left to right) - weird - Hey?

Could this mean that my CCU is defective? The fan will not run at all - at any level......

I did the AC Diagnistic test with the following values:

1=94
2=90 *
3=57
4=55 *
6=170 *
7=20 *
8=170 *
9=35 or 37 *
10=3.5 *

each test with an "*" means that the number farthest to the right did not show all the way - eg - value for test 9 was EITHER a 35 or a 37 - I couldn't tell because the 5 or the 7 (whichever it was) was not showing the complete number - digitally

I also got error codes:

B1234 - Sun sensor (B32)
B1235 - Emissions sensor (B31)

Should I change the sensors out next? BEFORE I ORDER A NEW CCU (for $889.00 USD)???

Thanks in advance for any help y'all can offer

I am in Phoenix today with a projected high of 104 F

thx
