Want to remove dash board from 2004 gmc 1/2 ton pick up need to replace speedometer an tac

it is located under the steering column. you'll only need to remove the knee board cover. it sits in a large bracket. see picture

run fault codes and look for a TCM problem or torque converter clutch fault.

Sadly, no. What has happened is that the tiny servo motor that moves the speedometer needle is failing. When I run into these we remove the dash assembly and send it out to be repaired, usually by a dealer although there are other companies that can do this too. Usually they replace all the servo motors and backlight bulbs during the repairs but make sure you ask if they do so just to be sure.

VSS can be bad and the 3 & 4 shift solenoid can be bad. Get a free computer test scan at any Auti Zone to confirm my findings

That is a manufacturing defect associated with your instrument cluster. My local dealer replaced my entire instrument cluster for free (truck was out of warranty) when my speedometer showed 100 mph in a parking lot and my oil pressure gauge read 0.

remove spider gears in the diff assemble which makes a clip available top remove then axle will slide out

you cant replace them it is easier to find a junk yard unit or send yours out for repair there is a printed circuit board that needs replacing too

There is a recall on the panel Cluster... call your dealer and have it checked out.. mention the recall... www.lemonauto.com

Have you checked the transmission fuse?

i think it could be bulb issue.

you have to remove the dash board and replace bulbs that are busted. replacing the bulb is no problem . the problem is taking the dash off. need to remove the dash cover first before you can remove the actual dash.

another thing to consider is the speedometer cable which is attached at the center of the gauge.

tnx 4 using fixya,
