blower motor stopped

I replaced my blower moter last month, and today on the way into work
(of course, on a super cold day) it all the sudden stopped.

I didn't smell any electrical fried smell, and there was no grinding
or squeel (or any unusual sounds)..it just stopped.

I have an 85 245, if that helps.

Personally, I'm hoping (and praying) it's just a simple grounding
issue. Not having heat kind of sucks.

 

How are the fuses? 240 fuses are known to corrode, it's one of the more
irritating aspects of an otherwise great car.

 

they looked fine, BUT I didn't check them out completely.

I did (and I just remembered this now) have a bit of a moisture in my
door issue, so there could be that.

I'm too tired to check it now (and for the life of me I can't find my
cover to show what one is what, etc..yes, I know it should be on all
the time, but I kept knocking off, so I took it completely off to
fix...only to forget to). But when I get a little more energy (or find
the damn thing) I will check that.

thanks for the insight.

 

The other really annoying aspect of this otherwise great car is the labor
for blower motor replacement. Praying for a corroded fuse. Oh, another
comes to mind: the wiring harnesses on pre-'88 models had brittle
insulation, causing bare wires to ground out. I don't know if this is a
common factor in blower motor stops.

 

I checked the fuse today, and it's fine. continuity fine, corrosion
no...

I don't want to take apart the dash again. But it sounds like I might
have to sunday or monday.

 

Check the ground wiring and the switch, it's pretty easy to take the console
cover off and get to the wiring.

A 240 blower motor replacement is no walk in the park, but after hearing all
the horror stories, it wasn't as bad as I expected when I did it. There's a
lot of parts to R&R but you don't need any special tools or difficult
techniques, just some screwdrivers, a socket set, work light, and patience.

 

the switch is new, and hte wire to it is new.

I just don't get why the ground (which was newly done) would go all
the sudden.

I never want to replace the motor again. I wouldnt' wish that on my
enemy.

I hope it's the ground. please....let it be the ground. I dread the
idea of re-doing this (not only cost, but time)

 

replacing that motor was a bear.

My friend, who's a volvo nut, didn't suggest anything about the wiring
harness (which I have).

 

Did you get stuck somewhere? The first one I did took about 4 hours, and
there were no greasy yucky parts to deal with. Once you pull the dashboard
(looks intimidating but it's easy) and center console everything is pretty
much out in the open. It's a lot easier than changing a clutch, oil pan
gasket, rear main seal, and other major jobs where you have filthy and heavy
parts, fluids, road grime, dirt and sand falling in your eyes, etc. It's
helpful to have some ziplock baggies to sort and tag all the fasterners as
you take them out. I've seen some guys do it with the dash in place, that
doesn't save any time, I don't even know how they get into the blower
housing with that method.

Now a job I wouldn't wish on anyone, try a headliner in a 700 sedan. I swear
if I ever do that again, I'll have the windshield removed first.

The new motor could be defective, but that's unusual. What's left is the
wiring. Check for voltage at the wires supplying power to the motor.

 

I took it apart without removing the instrument panel...but could not,
for the life of me, put itb ack in. so I had to take apart more of the
dash.

 

It was as simple as the switch plug not being in far enough.

One of the few times a loose connector has been a good thing!

Glad it was that easy for you.

Thanks. I timed it perfectly, as it's been super cold the last few
days (barely above 25 in the mornings).
