TOP 3 BUICK PROBLEMS

Power Window Failure

This problem is commonly attributed to Buick's LeSabre. Most of the time, one or two of the vehicle's power windows stops working-making them stuck. This happens when the plastic holding the regulator's cable breaks. Though there haven't been any recalls, and no practical solutions, the best thing to do about this problem is to replace the regulator with a new one.

To do the replacement yourself, you'll be needing: a 10 mm socket and 3-inch extension, a #2 Phillips screwdriver, a putty knife, a wire cutter, a door panel removal tool (available from any auto parts store), and a straight-blade screwdriver.

First, you should remove the dashboard's trim piece around the door handle. Once the interior of your door is revealed, remove the screw metal bracker by using your Phillips screwdriver. Pry out both the inside light assembly and the door panel, and then remove both the bulb socket and the two mounting bolts from the rear door controller. Afterwards, use your putty knife to remove the plastic vapor barrier. Then, carefully cut the cable attached to the lift mechanism. You should then push the window glass up (duct tape it so it wouldn't fall). Remove the window lift motor plug and then replace it with your new one. Be sure to test your windows before you reattach your door panels to save you the hassle of tearing your door back again.

Dashboard Failure

Also common to Buick LeSabres, this happens when the dashboard pulls away from the firewall. This normally happens since the dashboard is exposed to the sun's heat. Though incremental at first, you could notice that in a month or so the "peeling" gets worse-lifting your dashboard to more than an inch. To prevent this from happening any further, you should take your car to an auto trim shop and have it fixed (since it's a labor intensive job). Otherwise, a more temporary solution here is by using a very strong adhesive, smear it behind the material, and then use a small flat board and clamp it on to the dash to allow the glue to dry the dash back flat. Be sure to let the adhesive dry out before taking your vehicle for a ride.

Leaking Coolant from a Cracked Intake Manifold Gasket

Coolant leak is one of the most common problems from GM vehicles made from the late 90s to the mid 2000s. Experts commonly agree that GM's "DexCool" coolant reacts with the intake manifold gasket, causing it to leak. In any case, though GM has updated the material used on the gasket, there are still no signs for a recall. However, for you to solve this, you can get the updated gasket and replace the intake bolts with new ones that feature a thread locker adhesive. Take note, however, that you should consolidate the part numbers so you'd get a direct fit. Further, don't try to mix in a new coolant, though, as GM's DexCool isn't compatible with it.
