Q: Speedometer and Odometer not working, plus ABS and brake light is on

asked by on

A few days ago, I changed fixed the rear passenger brake light on my 2004 Jeep Grand Cherokee Laredo and the rear driver tail light. Once that was fixed, I went to change the bulb for my left turn signal, and then the front driver headlight went out. Then the engine light came on. It said I needed to replace a valve spring so I changed the whole coil and spark plugs. Then I changed the speed sensor and instrument cluster assembly, but the speedometer and odometer still isn't working. After those changes, the ABS and brake light came on. I went to NTB to get a reading for why those lights came on, but they were unable to get a reading from my computer. I'm not sure what is going on with my Jeep. Can you please help?

My car has 183583 miles.
My car has an automatic transmission.

Hi! That's a lot of random electrical issues! The speedometer/odometer/ABS problem may all have a common thread, however. The wheel speed sensor circuit is involved in proper operation of all of them. I would check that sensor and its connectors and wiring. If you need assistance, a certified mobile mechanic from YourMechanic can come to your home or office to inspect the issue.
