Is there an easy way to replace the heater fan in my olds delta 88 1975, it has started to make a howling sound and then stops, so for now i have just pulled the fuse, I cant see the fan under the hood, it must be inbetween the fenders
any suggestions would be appreciated
thanks

You really need a '75 Chassis Service Manual. Wildaboutcars.com has it online, and joining there costs nothing. However, the scans are not the greatest for some of the figures, and you'll want detailed figures.

The blower motor is mounted on the passenger side firewall, and removing it entails jacking up the right front of the car and removing the right front tire. You then need to cut into the inner fender with a linoleum knife to make a large-enough opening to remove the blower motor through that opening. The diagrams in the manual show where to make the cuts, and this is where the online scans are not clear, so an actual, paper copy of the service manual is a must.

How badly do you want to fix that squeak?

 

My old 76 Delta had the cut lines molded into the liner.

 

 

Thanks for the info jaunty75, i did as you suggested and joined the site wildabout cars.com, and found the info i needed, that is a great site.
The blower makes so much noise then it stops working all together.
Once i get the blower and check the size of it etc , i can buy one online at a site called drivewire.com
thanks again for your help

In my opinion, it is just as easy to remove the wheel and the seventeen thousand screws and just flex the entire fender liner out of the fender - then you've got plenty of room to work, and you won't have to patch the inside up.

Be sure to clean the ground connection and the ground point on the body.

I second this. When I acquired my '73 Custom Cruiser, the inner fenders had been removed for the repainting process, and they hadn't yet been reinstalled. Reinstalling them was not difficult, and I would expect that removing them wouldn't be any more bother than trying to cut a hole in it. By removing it, as MD says, you get a lot more room to work, and you don't mar it.

 

Thanks for that info also,i will check this out , sounds better than cutting a hole in the liner
I am new to this site just the other day, and i sure do appreciate all your input
thanks

Don't worry. You get old on it very quickly.

Look at me, for instance. I joined just an hour before you did, and now look how many posts I have.
