    Yes. battery and cables replaced by dealer.I have read other posts on the internet and it seems that the ignition switch could be the problem.

All my gauges just quit working. car still runs fine. they done this 2 or 3 times but would always start again. this time have not come back on. turn signals and dash lights work just no gauges.


At the moment, your instrument cluster maybe faulty? Due the basic tests, try to be sure. Check for applicable trouble codes relating to instrument cluster--pcm--communication codes. Some of the national brand auto stores in this country may check codes for free, if there are any.
Check voltage and ground circuits for the instrument cluster. The sending units for gages are wired to pcm then the pcm sends serial data to instrument cluster telling instrument cluster what to do with gages. If you want to check gage sending units, that's ok.

If you have a scanner that can communicate with instrument cluster, you can get instrument cluster to do a self-test. The self-test, the instrument cluster will turn warning lamps on and off, sweep gages w/o outside data input. The instrument is considered good, if it passes that test, if not, the instrument cluster is considered faulty.

Perform Diagnostic System Check - Instrument Cluster , Diagnostic System Check - Driver Information Systems or Diagnostic System Check - Audible Warnings before using the Symptom Tables in order to verify that all of the following are true:
• There are no DTCs set.
• The control modules can communicate via the serial data link.
Review the system operation in order to familiarize yourself with the system functions. Refer to the following:
• Instrument Cluster Description and Operation
• Indicator/Warning Message Description and Operation
• Driver Information Center (DIC) Description and Operation
• Audible Warnings Description and Operation
If you don't know about serial data communication an DTC'S I strongly suggest you take your vehicle to a Chevy dealer or an ASE certified repair shop .

Instrument cluster gauges


Check engine light ,abs , air bag lights etc.... come on when key turned on ?
Fuse IPC/HVAC BATT 10 amp located in the left IP junction block . Do you know where this junction box is ?
Does the heater an A/C work ? If so the fuse isn't the problem .
Speedometer
The speedometer is a road indicator. The vehicle speed sensor (VSS) is a permanent magnet generator which is located on the transaxle. The VSS sends an input to the PCM whenever the transaxle differential carrier turns. The PCM then buffers the VSS signal. The PCM transmits the VSS signal to the following components at 4000 pulses/mile through CKT 817:
• The instrument cluster
• The cruise control module
• The radio (uplevel)
The instrument cluster uses the input in order to indicate the vehicle speed on the speedometer.
Instrument Cluster Indicators
The BCM controls the instrument cluster indicators through the SPI serial data communication bus. Refer to Body Control Module System Check in Body Control System.

Warning lights stay on


It sounds like the ignition switch is signaling to the dash (in error) upon startup. It may be the switch itself.

1260 code wont start


P1260 - This, basically is indicating that a theft has occurred, and the engine has been disabled.If the engine stalled, during travel, and the code was pulled after the stall, this will indicate the following:

1.A loss of power, or ground wire to the PCM
2.A Faulty PCM power relay
3.A Faulty EEC power diode
4.A Faulty VERF signal.

Passive Anti-Theft System (PATS) communicates PCM through instrument cluster to enable or disable vehicle's engine. Within one second after engine start, PCM must receive an enable signal from instrument cluster or engine will be disabled. Along with enable signals, instrument cluster and PCM share messages that confirm security codes shared during initial installation. This shared security data makes instrument cluster and PCM a matched pair, so neither will operate in another vehicle. When system is functioning properly and ignition switch is turned to RUN or START position, THEFT indicator light will turn on for 3 seconds, then turn off. Vehicle will be enabled to start and run. If a problem exists in PATS, THEFT indicator light will stay on or flash continuously.


NOTE_ The best action is to clear the code, by using a diagnostic CPU. Plug the CPU into your in car port, under the dash. Follow the instruction on the CPU display to clear the code. if the engine dose not start after the code is cleared, this will indicate that there are some issues with the PCM, or PATS

NO START


This problem can be three things. The ignition switch is a good place to start but its under a recall and you should not spend any money on this repair. The passlock system next to ignition switch should probably be changed at the same time and is also under a recall. The instrument cluster is the most probable in your case. The reason i say that is because the key is the headlights not turning on you may also have some lights on the instrument cluster flickering on and off at weird times.The speedometer or other gauges are probably not working all the time. if you are handy you can remove the cluster and send it out for repair. The tech who repairs this might even tell you that the instrument cluster has nothing to do with non start issue but it does. the passlock anti theft reads the ignition key when you insert it into ignition cylinder. Once you turn the key the ignition sends a signal through the instrument cluster to the pcm. the pcm will allow the car to start if the correct signal is recieved. If the pcm recieves no signal it allows the car to start for a second and then kills the car.
