The sideview mirror on some 1995-2005 Chevy Cavaliers and Pontiac Sunfires may become difficult, or impossible, to adjust.
One possible scenario, according to GM, is that the mirror was inadvertently overextended by a parking lot attendant while trying to fold it to fit into a tight parking spot. The overextension leads to the T-end of the control lever jumping out of its slide, which causes the mirror to freeze in its tracks.
Reengaging the control lever to the slide should bring back the adjustment function.
Start the job by pushing the mirror as far forward as it will go. While holding the mirror in this position with your left hand, use your right hand and jostle the control lever until its T-end becomes aligned with the control lever slide.
To complete the procedure, slowly fold the mirror back while ensuring that the T-end of the lever is completely engaged in the slide. The mirror housing should now be firmly seated in its base. If it isn't, order a new mirror assembly.

Drivers of 1997-99 Cadillac DeVilles, as well as 1997-2002 Eldorado models, may complain of a vibration or shudder through the steering column and/or of a moaning noise during low speed turning maneuvers.
According to GM, both maladies are probably the result of normal steering system frequencies being transmitted through the original equipment power steering pressure hose. A new-design pressure hose, part #25755411, is now available to help eliminate the problems.
Start the installation by disconnecting the old pressure hose from the steering pump, then raise the car on a lift. Now working from underneath the vehicle, remove the hose retaining clip bolt. On 1997-99 models only, disconnect the pressure switch electrical connector. On all models, remove the exhaust shield retaining bolts, then the shield and hose retaining strap. Disconnect the pressure hose from the steering gear, then remove the hose from the vehicle. Remove the pressure switch from the hose, if applicable, for reuse.
On 1997-99 models, install the pressure switch into the new hose. On 2000-2002 Eldorados, install a new plug and “O” ring assembly, part #26021965, into the pressure switch adapter of the hose. On all models, connect the updated pressure hose to the steering gear and torque to 20 foot-pounds. Next, install the plastic retaining strap followed by the exhaust shield and bolts. Reconnect the pressure switch electrical connector, if applicable.
Continue the job by installing a new double-ended stud, part #11518592, into the engine block. Now position the pressure hose retaining clamp ends over the smaller end of the stud and install and tighten the retaining nut to secure the hose.
Lower the vehicle. To complete the installation, connect the pressure hose to the steering pump, fill the pump reservoir, start the engine and turn the steering wheel lock-to-lock several times to bleed the air from the power steering system.
