Default No Blower Fan- repost from 12/21/04

Same problem has resurfaced- 98 SSE. Auto Climate control- started car this morning- the Auto was already set to come on at 74 Degrees. The heat came on as the car warmed up- all normal- drove about 1/2 hour- turned the car off- DID NOT turn off the auto.- restarted the car about 15 minutes later after visitng friends- the auto came on etc lite up on the dash etc but the blower is not working .

Any help is appreciated. I really do not think its a fuse.

Thanks,
Chuck

I am not sure that things are gonna be the same this many years apart, but my '92 service manual says to look here first before doing a system diagnosis:

Check the instrument panel fuse block Fuse 17 by visual inspection
(Instrument panel fuse block is to the left of the steering column)

Check the Right Hand underhood Fuse Block fuse 3 by visual inspection

Check that ground G103 is clean and tight
This ground connection is located at the Right Hand Front of the engine compartment, above the RH horn
(An intermittent ground would explain your symptoms)

Check that blower motor connector and blower relay are mated correctly and firmly seated
(The blower relay is located at the Center rear of engine compartment, below RH underhood fuse block)

These components are probably the same 92 -98, but if not, post a request for some info from someone with a 98 FSM. Or, if you don't want to wait, check out E-Bay or the web for a set for yourself. They usually cost about $50 - $100, but they pay for themselves quickly in diagnostic procedures.

Hope this helps

Thanks Bill- Checked out all areas that you described- could not find anything that appeared wrong- the problem still exists- Blower fan worked on Friday- konked out on Saturday-
worked on Sunday- stopped working this morning- started working again this afternoon-
Going in for repair tomorrow with my local mechanic- I need heat, especially
with very low temps here in the Northeast lately. I can't mess around with this any longer.

Everything seems to point to the blower fan motor as being bad.

i'll repost after its fixed etc.

Thanks again,

Chuck

Sounds like the blower itself. Mechanically. Fried bearings? Binding shaft? SOUNDS is the key word.

The Heater Motor had a BAD SPOT on it, causing it to run intermittantly.

New Heater Motor installed, I GOT HEAT!!!!!!!!!!!!!

Thanks to all who responded.

Sorry I missed this...glad you got it fixed.

I had a similar problem, mine cut out when turning or leaning right and sometimes wouldn't work at all. Someone here suggested I give it a hit with a broom handle and it started right up!

Like you, I changed the blower unit and have lived warmly ever since

Cheers,
