TIPMs — also known as Totally Integrated Power Modules — control the electrical system in your vehicle. Unfortunately, you may not immediately be able to tell if your TIPM is failing. Like other failing parts/components on your vehicle, issues related to a failing TIPM may only show intermittently, making it hard to pinpoint as the culprit.
Common Symptoms of a Bad TIPM
Starter cranks but your vehicle won’t start
Horn inoperable or randomly honking
Power doors unlocking or locking themselves
Transmission is in “fail safe” mode
Airbag light is always on (without any codes)
Windshield wiper issues (not working, randomly wiping, etc)
These symptoms could be caused by a bad TIPM, but before replacing your TIPM you may want to verify that power is reaching it without any interruptions.
