Pontiac Bonneville Windshield Wiper Motor Problems and Their Causes
Rainy days are no problem with your Pontiac Bonneville windshield wiper motor running the wipers of your vehicle. If a malfunction occurs with this part, expect low visibility and a lot of hassle during harsh weather. So what are some of the problems affecting wipers motors and what are their causes? Read on to find out.
The Bonneville windshield wipers do not move at all.
If there is no movement from the windshield wiper motor after activating the wipers, chances are, no electricity if flowing to the motors. Mostly, this is the result of a burned fuse and is easily fixed by replacing it with a new one. A more complex issue is a damaged or grounded wire, which may take a significant amount of time and effort to locate.
Some wiper modes do not seem to work on the Bonneville.
This is a weird problem that usually affects wiper motors. Putting the wiper in one mode will activate the motor while putting the wipers in another mode will not. For example, the wipers will work as normal when set to low but will then cease functioning when set to high. Problems like these are usually caused by malfunctioning electrical circuitry, usually a broken circuit board or switch. Fixing the problem may be too hard and complex for many and an easy fix would be to replace the appropriate components instead.
The wipers of the Bonneville move slowly or even barely move at all.
This problems can be caused by a faulty electrical system caused by damaged wires or a worn out motor relay. Replacing the components with a new one will usually do the trick. Other times, it is the mechanical components of the wiper motor itself that are failing. At best, the joints and moving parts of the motor can be lubricated to allow them easy movement. At worst, the whole motor may have to be replaced. Slow movements may also be cause by solid objects that have managed to jam themselves into the motor or any other moving part of the wiper. Taking out the offending object iwill do the trick in this case.
