Loosing Tachometer and Speedometer while driving?

[ptparker]

Over the last week I am intermittently l my tachometer and speedometer while driving my 2004 Trailblazer. When I turn the car off and on sometimes both come back and sometimes only the tachometer comes back. Any ideas on what could be wrong???

Welcome to AF. Should be scanned to check the possibility that the speedo cluster is a problem, or loose connections if the scanner shows intermittent speed or rpm drop out there is another problem not the head.

Yep. If you are not getting any driveabilty concerns or DTC's, it's probably a loose connection on the instrument panel cluster, or a failed IPC all together. No unheard of on the GMT360 that's for sure!

I own a 2003 Chevy Trailblazer which I have been having a problem with since 3 months after I bought it. At first my speedometer would stick and flutter. Unfortunatly it didn't happen consistantly enough where the dealer could diagnosis it. At the begining of this year the gas gauge quit working all together, I took it to the dealer and they stated it was a cluster problem. Over $500 to fix. I am aware that there is a extended waranty being offered to Silverado, Tahoe, Avalanche and Suburban owners on their clusters for this exact problem. Chevy states they have not received enough complaints to include Trailblazer. My suggestion- voice your complaint and help us all.
