Just installed new blower motor (yes it is in the correct way not backwards)
and I stll get tepid air flow out of the vents and defrost.
What direction should I go, car heats up but it takes too long with no air flow
Thanks
David

Is it an airflow issue or a fan issue? Does the fan get louder when you hit "high"? If not, it could be the blower regulator or the push button unit.

It stays the same. What can I do to determine which one to replace

on 124 mercedes got fuse on left fender look for one
or the rezistor undernet fan

It's probably the regulator under the fan. I don't remember off hand how to test it before condemning it (I think it's pretty pricey), but I know it's been discussed in the forum.

Hi David,

I had a similar problem and the blower regulator was the culprit. I
found a used one on eBay for $40 and put it in. I talked to my indy
mechanic about it later and he suggested not using used parts when
it comes to anything electrical.

There's a company in Atlanta that sells rebuilt ones. I can't find the
contact details but if you do a search on regulators you might find it
mentioned here.

Bill
