1999 GMC Jimmy Repair Question
SPEEDOMETER TROUBLE AFTER CHANGING INTAKE MANIFOLD GASKET
During removal installation of the manifolds, wireharness have to be removed and probably some ground connections too. Ensure they are correctly and securely reconnected.
WENT OUT AND CHECKED ALL CONNECTIONS COULD NOT FIND ANY LOOSE OR INCORRECTLY INSTALLED ANY OTHER SUGGESTIONS WOULD BE GREATLY APPRECIATED THANKS GARY
Try checking for trouble codes first.
THERE ARE NO TROUBLE CODES
If no codes are thrown and speedometer is not working, problem should be at the meter cluster.
THE METER CLUSTER WOULD DEVELOP A PROBLEM JUST OUT OF THE BLUE AND JUST SHOW UP AFTER I CHANGED INTAKE GASKETS ETC? THANKS GARY
It should not but then again coincidences do happen.
IS THERE A WAY TO TEST THE METER/ CLUSTER? IF SO HOW DO I GO ABOUT DOING IT. THANKS GARY
The trouble code P0500 diagnostic procedures should help you on the diagnostics.
Which engine do you have?
THE ENGINE IS A 4.3 L
