My 1992 buick lesabre is giving me problems with my heat. I have heat, but my fan is not pushing it out, and I can not hear the fan working at all. I'm pretty positive that the fan is not working but am unable to find a. The location of the fan and b. Am not sure if there is a fuse/relay for it that I might be able to change out. I did change the main board but that did nothing to help the situation. Could you please tell me the location of the fan and or relays? Thanks a bunch!

The fan is mounted under the hood, passanger side. I have attached a picture. Before replacing anything, check to see if there is power going to the motor. If there is, the motor is bad. If there is no power, there is a blower motor relay and resister that could be the issue. Check the motor first, and let me know what you find.

We found the heater fan. Thanks so much for your help. We already replaced all the relays, so we're pretty sure its the actual fan itself. I do have a question about my brakes on my car though if you think you could help me out. The power booster went out on it, we replaced with the another one, and a new master cylinder. The new master cylinder blew the rear seal in a matter of two weeks, so we just put another one on, (brand new) and now we are having trouble getting the pressure to build up. If I rapidly pump the brakes, the pressure WILL build up, but it takes a good 5-6 pumps before it starts. We bleed the master cylinder last night and its still doing the same thing. We've checked all the lines, and there are no leaks from any of them. What should we try next? Bleeding each brake individually? Also too, by the time I drove approximately 8 miles, I was already low on brake fluid after having topped it off before I left. This has been an on-going battle in this car, the brakes. We only have 2 lines coming off the master cylinder and then it splits into the 4 lines and it seems like only the rear brakes are actually grabbing. What route should we go next? This is really becoming a hassle. Lol. All I want is a car that has heat, and that will stop when I need to stop. LOL. Any advice will be gladly accepted! Thanks again Joe. Jody

Glad to help. Did you bench bleed the master cylender prior to installing it? Also, did you bleed all brakes starting at the furthest point from the MC and moving one at a time to the closest? Finally, did you properly adjust the rear brakes and when you pump the brakes up to get a pedal, does it stay firm or slowly drop? Oh ya, one more. Without pumping the brakes, does the pedal go to the floor?

Let me know,
Joe
