I was wondering if any of y'all have had your speedo's repaired/replaced and if so, where did you have them done. (Other than dealers of course). I want to get my speedometer upgraded by Granatelli, but I need to get it fixed first.

I am looking b/c my speedo, tach, fuel gauge, odometer, fuel pressure, and temp gauges do not work first thing in the morning and then later in the day as things get warmer, they all work, (strange, huh?).....
So all i got in the morning is my voltimeter.

 

Sounds like the 99 gauge cluster problem. There's TSB from GM on it...

Trip Odometer Resets to Zero (Exchange/Install Instrument Cluster) #99-08-49-009 - (Jul 23, 1999)
Trip Odometer Resets To Zero (Exchange/Install Instrument Cluster)
1999 Chevrolet Camaro

1999 Pontiac Firebird

Condition
Some customers may comment that the trip odometer resets to zero when starting the engine.

Cause
Ambient temperatures below 0° C (32° F), combined with low battery voltage, may cause the trip odometer memory to be erased when starting the vehicle.

Correction
To identify the instrument panel cluster part number, use the following procedure:

Install Tech 2 and from the main menu screen select F0: Diagnostics, press enter:
Select 1999, press enter.
Select Passenger Car, press enter.
Select F1: Body, press enter.
Select F, press enter.
Select the Proper nameplate, press enter.
Select the Engine, press enter.
Select F1: Instrument Panel Cluster, press enter.
Select F1: Data Display, press enter.
Select F0: Module Info. press enter.
The Tech 2 will now display the instrument panel cluster part number. If the part number is shown in the table below as the old part number, install a new part number exchange cluster which has had the new circuit board with the non-volatile memory chip installed. Order the cluster from your A/C Delco® Service Center. DO NOT ORDER A CLUSTER FROM GMSPO.

Here's a couple threads on the problem:

I think in this case, the dealer is going to be the quickest and easiet fix. (Taking to another shop would require buying a guage cluster, finding a shop that can flash the new cluster to match the miles on your old one - if any place other than a dealer can even do it - and then getting them to install the new cluster.)

 

well, I had hoped to avoid my dealer, as my car is way out of warranty, and that I was informed that if there needs to be any sort of real work done to the cluster, it would have to be sent to NY for it to be done. I am still weary of dealing with my local dealer as they botched a rear-end install on my car and I am still fighting with them to get it right. You think that after shelling out hundreds of $$ the dealer would have someone who knows what the F@#% they are doing working on your car.

Anyways, thanks for the info...
