Question about 1994 Buick LeSabre

Open Question

1994 Buick LeSabre Limited electrical problems (heater settings and radio controls). The heater temperature setting will change by itself. It will go all the way down to 60 or up to 90. It will switch into auto mode and turn the fan setting up or down. The heating system will turn itself on after being shut off. The radio will change station settings. It goes into the seek mode(?) and switches to another frequency or switches from AM to FM. It changes the volume settings all the way up or down by itself. The displays on the heater and radio will flicker slightly before going into one of it's electrical spasms. I looked for any corrosion at the ground connections at the R & L chassis wiring (under carpeting by the door openings) and the wiring connections for the ECM but found nothing.

SOURCE: Replace Cruise Control Switch in Steering Wheel

I am describing the procedure for the "On/Off" switch, I did not try the one you mention. Buy the switch anywhere ( about $15 ), then use a sharp tool ( small knife, screwdriver, anything ) to gently pry the old one from its socket. It is not glued or screwed in or anything, just squeezed tightly in the socket. Once the switch is out, pull the cable, connect it to the new one, insert back in the socket and press gently. No force necessary, it comes out easily.

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.

It sounds like a actuator is bad or not getting proper vacuum to open or close on demand.

Either the controller is not moving the valve or your heater core is clogged and needs to be back flushed.

Jump started the car. now interior lights won't come on when I open the any doors. Lighte will come on manually with the dash switch. Changed the fuses under the rear seat to no avail. worked fine before I...


Since your car was the one getting jumped there should be no damage,all I can think is if the batt. was flat dead it may have changed the settings on the body control computer,I would suggest
looking in the owners manual for dome light options ,I think the radio is the "remote control" for a lot of owner options like that.
Also make sure the chassis ground ( the smaller black wire on the neg.batt. terminal) is a good connection.

Just bought a nice used '92 Buick LeSabre Limited. NO Owner's Manual! I can't figure out how to set the damn CLOCK! Anyone care to fill me in on this??


Turn on the power knob for the radio/clock. Wait until the clock display shows up. Press "set" button and use the 'Scan' and 'Seek' buttons to set the time.

Good Luck

I need a new radio, not sure which one.


Go to a scrapyard and buy a radio that comes from the same car you have, with the same steering wheel controls. The only difference will then be that the new one works. make note of any security codes and get vin# from vehicle radio was removed from so that anti-theft feature will not prevent it from working. Radio and wiring harness will not change if you obtain radio from identical vehicle.
