Dealer Ripoff?? Blower motor regulator question
My dealer is replacing free under warranty my blower motor that squeels a little bit and wants $500.00 to replace the blower motor regulator. Just how easy is it to replace the regulator if it goes bad?

What year & model?? Some parts are $$$
For example the W140 chassis regulator 140-821-83-51 lists for $320.

1993 300e 2.8L. I brought the car in because of a squeel that rarely occurs and because I thought the warranty would cover it. Well, the blower motor is covered but the regulator is not. The dealer is saying "I'd hate for the reg. to be bad, then I'd have to charge for 2 or 3 hours of getting to the reg to replace it."

On the W124 chassis the blower reg is 124-820-27-10 & lists for $286. Takes 5-10 minutes with the blower motor removed!!

I'd take my chances. The 124 regulators aren't near the problem the newer ones are. I attribute that to the huge heat sink that also makes them the most money.
The blower does have to come out to do it but labor is small compared to the part.

And it take 3 hours labor if they have to go in without the blower motor removed, right?

I'm with Steve (not that my opinion counts for a hill of beans relative to his...). The blower regulator has not failed - the fan works and changes speed just fine, right? If so, the regulator is just fine and you need a new fan minus the squeeky bearings.
The regulator is located directly under the fan; the fan must be removed to change it. The regulator itself is just a small box a few inches square with electrical wiring connected. It takes no more than 10 additional minutes to change it out with the fan removed. Three hours sounds kinda high to change a fan on a 124 chassis car. I've had the fan out of mine once, and it didn't take two hours - and that's the first time I ever did it. - JimY |

If you are a DIY you might do yours without large cost
If you want to search my (DanielW) posts on 300E blower, You might be able to lube the bearings on the fan and even replace the brushes if they are more than half worn down. I really don't know if many people have long term success with that sort of thing --- but I was able to do both repair jobs on an 87' 300E by using laquer thinner which had assembly lube disolved in it. Also created some new brushes from an alternator brush set which was a small amount larger than the stock ones. Brush carbon material sands down really easily and you solder on your wires from the old set. My total cost was $2.00 and about 4 hours tinkering time. Good Luck to you, DanielW

It's not likely to be the regulator IF speed still varies.
I should have added that on the earlier post.
