So David,  Whats wrong with a volvo that has no interieor heat in the  heater

and does not seem to get to operating temp on the gauge

David,  does your 92 volvo coolant system fill through the top of the radiator or does it have a plastic expansion tank that you fill.

I ask these questions cause my volvo is in Boston.

SC,  Expansion Tank on the rt. front .  I would bet on a thermostat also. My little girl's Volvo didn't have heat and she didn't tell me about it until I drove it. The gauge never went up at all. Turned out to be the thermostat that had fallen apart.

let there be heat,   He took open the heater vlave an it was all clogged up with bars leak.   SO we have heat.  which is good.

The bad thing about having your brother pick up a car for you ,  is that his girl friend  might take a liking to the Volvo.  Which seems to be happening

So maybe our Volvo is going turn into a Chevy Lumina,    SC

Why is the control valve plug up with Bars-Leak?

To fix the leaking heater hose...of course! :lol:

Between me and another friend of mine, we might have parts that any of you fellow Volvo owners may need. He bought an '86 Sedan and I have a spare '88 Wagon. We haven't gotten into either of them yet, cause we're going to use one to fix the other.

I spent about 7 hours last night fixing the blower motor for the heater. Not an easy nor fast job. It might be if I have to do it again, but for the first time, it sure took a while.
 
I started out just wanting to test the switch and see if power was getting from it to the motor. I figured out that there was power going through, so the next step was to get to the motor, find the ground wire and see if it was all proper. Taking the blower shroud off was difficult, with all these little clips holding the halves together (Sproing! There goes one a-flying!) and maneuvering the half on the driver's side past all these wires and out of two duct connections. Got the motor out (had to remove both fans) and tested it for continuity and power. No continuity and no power. Took the motor apart to see if the brushes were wore out. The inside was caked with black powder. The brushes looked ok. I cleaned it good and put it back together. Tested for power, and had a working motor. I guess it just needed cleaning. Reassembled and now I have a working fan motor and blowing heat.

I skipped a lot about removing the center console, the instrument cluster, the glove box and even almost took out the seats for more wiggle room. Then finding blown instrument bulbs, accidentally pulling off a vacuum line for the pneumatics that operate the Heat and AC re-circulation and diverting switches and levers (Only discovering that after the console was back on). All that took a lot of time. I had this job quoted and the estimate to replace the motor, resistors, and switch was $800! I believe it. If I was to it I wouldn't take less than $600.  

I'm sure that the motor and components will have to replaced some day. At least I'll know how to do it then.
