300 E heater Quit!!!!
 

1989 399-E heater quit on me yesterday. None of the switches will turn anything on. Checked out all the fuses & the two in the relay section and are OK. Seems like an electrical problem. where do I go next. I would Estimate parts on heater motor or controls $250-300 plus installation. what should I check before giving up on this car?

Car also needs new water pump,tensioner,a/c compressor.
I'm ready to think about a change. Owned car for 4 years, rebuilt head last xmas but it runs ok. Too much for a rough car with 210K on it .

suggestions?

My ventilation fan quit on our '91 300E about six months ago. I did the same checked fuses etc. I was dreading the fan motor replacement.

It turned out to be the fuse link. Its holder is about an inch long, about a 1/2 inch wide. It is an odd black plastic part near (in front of) the fuse box. It has two fairly heavy-duty wires going into it, one on each end.

Pry open the cover and inside you will see what looks like a flat piece of metal. These fail and will even look to be OK.

I might have a picture of its location if you can't find it.

Mike,

If your blower suddenly stopped, it's most likely one of the following:

- push button control unit
- blower motor regulator

Unfortunately both parts are quite expensive. Do a search on "blower motor" and you'll learn how to test the system to pinpoint the problem.

If you're lucky, it could be the fuse as haasman indicated.

Good luck

haasman , that's for the info ,will check it out.

Paul how's the head job. holding up?

try this.while the car is running wiggle your ignition key a little.alot of the time the ignition switch is loose and won't power up the blower. or check the bar fuse on the inner fenderwell mention in previous post.
