Rear defrost on 97 buick lesabre not working

I drive a 1997 buick lesabre custom and the rear defroster stopped working last spring... naturally, I put off fixing it until the first snow this year reminded me that it was broken. The light in the dash still lights up when I try to turn on the defroster, but no melting in the back window.

So far I've taken a multimeter to the back window and I am getting voltage to the plug in the back window where the defroster connects. I even get voltage on the other side of the window where the defroster grounds to the frame, so I think the problem is not in the window itself.

The fuse is good, but I don't know where else I could be loosing the amps necessary for the defroster to work right.

Thanks for your suggestions!!!

    My rear stop lights are not working but the stop light in the back glass works properly. What could be causing this problem. I check voltage at the lights and there is no voltage unless I remove all the rear bulbs.

Your problem is in the window..........if you are getting 12v to the wires that connect to the window the lines in the window must have a break in them ............. they must conduct the dc volts to complete the circut, the lines heat form the voltage running through them thus ridding your window of fog and ice
hope this helps...........thanks for choosing FIX YA!

AC BLOWING THROUGH DEFROSTER VENTS


on the controls for you AC there is settings that send it where you want, floor, dash, vent, defrost. choose vent. Also notorious for vent doors getting stuck from dirt, leaves etc going down the breather under your hood on top the rear fire wall down the holes and clogging the louvers so they cant switch over. check the setting but if not, this is really a job for buick. pretty complicated and risky to mess with for the novice machanic.

Buick lesabre 97 car alarm goes off for no reason why?


Most likely, you have a vacuum leak if steam is coming from your defrost vent in a 1997 Buick LeSabre. There are approximately 600 million passenger cars worldwide (roughly one car per eleven people). --------------------------------------------------------------------------------------

Rear defroster lights up, but does not defrost, also very weak car radio reception.


Between the rear passenger window and the back window is a junction where rear defrost wiring and radio antenna connect. Rear defrost wiring becomes loose and burns this unit out. when looking for replacement at salvage yard everyone of them I found had burned up. Lots of La Sabres w/o working rear defrost. I made solid connections for defroster, and added an antennae, not much point in repeating a system that will fail again.

Can the air struts {rear}97 buick lesabre be replaced with standard struts, no air ?


Yes, but the cost may be more than it would cost to replace the air bags. I'm not sure, but I believe that on your vehicle there are springs with struts. But, yes, you shouldn't even have to drill holes, they should already be there.

Back defrost don't work on 97 buick park avenue


Regarding the repair of the rear window defroster. There is a "electric ACD module" on the inside rear driver side roof sail that connects to the rear defroster and antenna. I had the same problem and found the connector for the defroster had overheated and melted resulting in a failed connection. The NAPA part numbers for the module and replacement connector are 25623688 and 15305949.
