    Neither one. It has freon, new relay, new resistor, and the fuses are good, but it's still acting up.

the fuse is in panel with other fuses,however it will say a\c instead of heater. You may want to use a test light to check for voltage at the blower motor plug. To see if current is going to the fuse. Check the other fuses too. since they are linked in parallel to the the acc auto climate .

SOURCE: 1994 buick lesabre heater core removal

The heater core is located under the dash, in the center. The container holding the core looks like a black plastic box. Remove the ash tray for easier access. You may have to also remove some other covers under the dash. You must first drain the radiator then you have to disconnect the hoses. There are two hoses connected to nipples of the heater core that go thru the center of the firewall. Remove the screws that hold on the cover to the heater core. Then you should be able to get the old one out. There might be a couple of other minor steps but I'm sure you can figure them out. For re-installation just go in reverse order to put it all back together.

My 92 Le saber did that and we changed resisters and did a number of things and nothing worked Finally my mechanic put a bypass switch some where on the power line and after that it worked.

You do not want to do this as you would likely cause compressor failure. Fix the issue, not the symptom.

AC/heater fan on 1992 Buick LeSabre only works intermittently


Could be a bad control switch, relay or connection and ground at motor itself. Since it's intermittent, check voltages when it's working, then again when it's not. Wherever voltage stops, that's what you need to replace. Don't wait on this...when completely inoperative it gets much harder to find the problem!

Serpintine belt


Only the dealer will have the pulley, it is very straight forward, hooks up to the same holes as AC compressor, the belt diagram is under the hood near the emission sticker, that is easy as well, but you will need either a large 3/8" or 1/2" ratchet to release the belt tensinoner pulley.
