I hit a pot hole pretty hard and my speedometer, tach, and odometer gauges no longer work. They will randomly flick on and start working for very short periods, but never for long. Also, my brake light remains on, i am pretty sure that my ABS no longer works (that light remains on) cruise control stopped working and climate control no longer works, and it all started after the pot hole, any ideas??

 

Is you CEL light on?
Check for any engine codes...
Sounds almost like a loose wire/ECU harness... but then again I'm no expert.

Some things to consider when trying to figure out the problem.
-your brake/tailights are on? not sure why...
-Spedo and tach signals are sent from a speed sensor (on 3rd gear) from your transmission to ECU to cluster. Signal is also used in Cruise control.
-Wheel speed sensors (for ABS) are located in the wheel bearing/hub. Errors in these will shut off your VSA and ABS.
-Some climate controls runs through the ECU

 

me too
the only thing that works is the gas gauge
help

 

I think it could be the Modulator Assembly

 

so if it is a loose ecu harness, where do i look to see if its loose?
