I'm currently troubleshooting an issue with my car's wiper system and could use some advice. Despite replacing several parts, I still don't have functioning wipers. Here's a breakdown of what I've done and the symptoms I'm experiencing:
What I've Replaced:
- New wiper motor (Note: I've switched out the wiper motors but lost track of which one is the original and which is new. The "new" one is from a '02 M3, while my car is a '04. I believe the gear covers are different, so I should be able to identify them.)
- Replaced the stalk (wiper control lever), but this did not resolve the issue, so it can be ruled out as the source of the problem.
- New wiper relay
- New 30 amp fuse located in the glovebox
Additional Details:
- I have bench-tested one of the motors, but due to the duration of this issue (5-6 months) and my busy schedule, I've forgotten which motor I tested.
- I plan to remove the wiper motor currently in the car and bench-test it as well.
- Additionally, I will disconnect the motor, put a new 30 amp fuse in, turn on the wipers without the motor connected, and see if there is a short. If there is, it should cause the new fuse to blow.
Symptoms:
- Intermittent Operation: Initially, pressing the wiper stalk down sometimes triggered the wipers to function. This was inconsistent.
- Erratic Behavior: When it did work, I intended for a single pass, but the wipers would make multiple sweeps and then stop arbitrarily mid-windshield, never in the same position.
- Temporary Fix: Turning the car off and back on seemed to temporarily resolve the issue, allowing for one full pass of the wipers upon pressing the stalk down.
- Fuse Blowout: On one occasion, immediately after replacing the 30 amp fuse and activating the wipers, the new fuse blew.
This problem has been a bit of a head-scratcher for me. Here are my queries to the community:
- Has anyone encountered a similar issue? If so, what was the root cause in your case?
- Could this be a wiring issue I'm overlooking, or is this indicative of a more complex electrical problem?
- Could this be a GM5-related issue?
Any advice, suggestions, or shared experiences would be greatly appreciated.
Thank you in advance!
