heater blower motor is howling[ALL/1998] posted by Greg Stenzel on

My 83 DL blower is howling...time to swap the motor, I believe...
my 80 DL required an entire retrofit of the blower system..
does the 83 just require a new blower motor, or a retrofit as well?
From the diagrams in the Chilton, it appears that the center dash and both sides of it need to come off...gradual deeper disassembly to get to the motor...
any other hints on doing this job?
Regards,
Greg

You dont need to buy anything. Take the motor out of the heater case and grease the bearings. Will be as good as new. Its about a 5 hour job tho to remove motor and replace. So if you dont do it yourself your costs are all labor.

Try this first.-remove the center console trim panel to expose the metal
panel that is in front of the blower motor. Drill three holes about3/4"
apart horizontally-one at a time-use a bit about1/8". Drill the first hole
in the middle and look and the second offset 3/4". Use a penlite and shine a litethru one hole and look thru the other. You will see the blower motor
riding on its bearings.Drill the third hole to the opposite side to see
both right and left bearings. Use a small plastic straw- the kind that
comes on top of aerosol-to apply a small amount of ATF to each bearing.
I rigged up a syringe and tubing as an applicator. You use all three holes-
one to shine the lite thru, one to look thru, and one to apply ATF thru.
Apply a small amount and try the motor.If it quiets down you have saved
yourself 4&1/2 hurs of labor. I did this on my 1984 240 and it lasted for
over 2 years of quiet service.
I can't take credit for this- IPD ran a tech tip in their newsletter.
Thanks to Scott Hart & the gang for the excellent advice!

IF you have to remove your heater, take it out sideways.You dont have to remove the centre console.Remove the glove compartment instead.There is just exactly enough room to pull it sideways.When you have done it 4 times ( because of bad replacement parts from junkyard!) its actually possible to replace the complete unit in less than 2 hours.
Hope your not getting such a bad experience! Good luck with the lubricating had never thought about this myself.Let us know if it works.

If your do the repair, don't forget to change brushes. Buy a new ones (universals from parts store)and solder to the motor. (If only brushes are bad you can change them by making a hole to the cover. No need to remove anything) Henrik - we have A WAY MORE stuff on US spec cars than your Euro one! Lots of AC stuff takes more time...

Got to admit,had never had my hands on a car with ac so i dont know about that.
The heaters i had changed was all what volvo calls a combined unit(cu).It can only deliever warm air and fresh air, and i guess that is a lot more simple than a unit with ac.Checking my 240 - 260 parts catalogue - Topi you are right, with ac the unit looks quite a bit more complicated.

Sounds like an orthoscopic procedure to me. My question...I am a relatively new second owner of a 1984 Volvo 240GL Diesel with 68K. I have read a lot of threads about the blower motors and the arduous task involved in R/R work. Although my blower motor does not exhibit any problems at present, I am wondering if these problems are age related, use related, destined to occur, typical of any particular climate (more heater use than A/C).
If the described procedure works, could it be used to do preventative maintenance to avoid the problem all together? I could understand not tearing everything apart to do PM, but if there is a relative painless procedure, would it be wise to PM in that case? I really like to avoid pain at all possible junctures.
Thanks for any comments.

Bri,
Just a minor point on car model designation protocol. You say you own a '84 240GL diesel. I always thought that the second digit of the model indicated the number of cylinders, and the third digit the number of doors. For example, my first Volvo was a '74 142; had 4 cylinders and 2 doors. My third Volvo was a '78 245 DL; had 4 cylinders and 5 doors (wagon). My fourth is a '88 240DL wagon; 4 cylinders, but I think they dropped the door digit along the way.
So, here's the question: My second Volvo is a '84 260GL diesel; 6 cylinders and 4 doors, door digit no longer used. Does your '84 diesel have only 4 cylinders? Just curious.

Dave,
You know, I have looked on my car and really can't find anything that indicates a number (240 or 260). The front of the owner's manual is missing. The insurance company and the dealer call it a 240. The motor vehicle department calls it a DG4. I always assumed that the 24 part stood for the displacement, but as I look through the variant engines over the years, this is incorrect. You are right, they did drop the last digit to indicate the number of doors, don't know why. Maybe those extra man-hours stocking and affixing the extra digit was lowering their profitability. My car has the straight six D24 diesel engine (145 cu in or 2.383 L). It is a four door. The trim level is GL (interior/exterior). The emblems on the back simple say VOLVO on one side and DIESEL on the other, no numbers. Just assumed it was a 240 because that is what it looks like.

You know, I may have to eat some Swedish crow, here. I have reviewed all my owner documentation, including the dealer window sticker (of "sticker shock" fame) and it only refers to the car as a "GL Diesel". Even my official Volvo workshop manuals don't use the number designations. In fact, the shop manual page describes '84 USA models as follows:
<
DL: 2-, 4- or 5-doors (wagon). Equipped with B23F engine (with LH-Jetronic II fuel system).
GL: 4- or 5-door models with engine B23F ( with LH-Jetronic II fuel system).
Diesel: 4- or 5- door models with D24 diesel engine. Based on GL body, except for taxi version which has DL base.
Turbo: 2-, 4- or 5-door models equipped with B21F-Turbo engine. Based on GLT body, except "Police" version which has DL base.
>
Even more confusing, I reviewed all my Volvo dealership service invoices and seen it called a 240, 244, 260, and 264. Clearly, we are not the only ones confused, here.
I propose we end the thread now

As mentioned earlier... 200 series=the box. 700& up=the wedge. Diesel desegnated:DIESEL Another reason to buy 700 series(except for the biodegradable wiring harness) 30 min to remove and install the heater blower.

This is a common problem on older 240's. My motor lasted two years after the lube job, but eventually gave up and had to be replaced. The replacement is
made difficult by the fact that Volvo no longer makes the same blower
motor and the housing must be modified to mount the new style. Plastic nibs
protruding from the mounting bolt holes inside the housing must be ground off flush to mount the new motor. I have used a die grinder and a Dremel tool
to do this with good success. This is a messy and time consuming repair.
I wouldn't do it for less than four hours of labor.
Maybe a pre-emptive strike with lube would postpone it even without symptoms.

I removed the motor and sent it to a fellow in Canada. He repalces the OEM bushings with bearings and rebuilds the motor. It is about 100 bucks and it works better than the original. His name is Bill Cheb. If Volvo had used bearings to start with, this howling would not even be an issue.

Bill Yarbrough,
Can you provide a way for others to contact this Bill Cheb in Canada?
Thanks in advance.

I can not find the receipt and have deleted his email address. It is listed in the archives under subject heater fan and my name. However, I could not get the archives to show the message. Maybe you can. I will keep trying to find the info.
Sorry
Bill

Bill Cheb does a beautiful job rebuilding fan motors by replacing the sorry OEM bushings with bearings. This will make the heater fan motor better than new. His email address is Bill.Cheb@UAlberta.CA
