The problem is in the connection of the cables in the ignition switch. uncover the lower or bottom cover of the ignition switch and get a flat screw driver and a hummer and hit it exactly where the cables connect to the ignition switch cylinder or mechanism. if that doesn't work then you have to change eather harness or ignition switch mechanism.

Speedometer went haywire and car stopped


define haywire.?

dead, off, and is odometer off too?
stopped, you mean the car stalled?

when the engine stalls you see the following (driving school 101)
1: quiet , now. from engine.
2: steering and braking get harder. up to 6 times harder.
3: RPM tachometer shows 0 RPM.
4: Speed drops and lands on zero as car stops or you run out of down hill free right.

so did engine stall? does it restart,?

D4 light started blinking, speedometer stopped working and mileage gauge


Vehicle speed sensor. Top of the tranny is a connection. From this, a cable runs to the back of the odometer. Probably need to replace it

The speedometer and tachometer problem on your Trailblazer instrument cluster is very common on the 03-06 models. It's caused by failing stepper motors on the cluster's circuit board and can be fixed. Check out this page for more on how to get it fixed - Trailblazer tachometer problems

Speedometer not working


This may be the issue:

Both the speedometer and tachometer have a mechanical stop for the needles. The stop is located behind the display board.

The stop and needle contact point tend to develop a sticky residue which mechanically prevents the needle from rising above zero. At the behavior would indicate, the needles independently of one another, tend to stick at zero, yet intermittently, while driving will resume normal reading.

Disassembling the instrument cluster and carefully cleaning the stop and needle contact point with some solvent on a bent cotton swab or pipe cleaner should solve the problem. Just be careful not to break any of the delicate parts.

This problem and solution were first posted by users on the ClubLexus forums, but the brief discussion is difficult to locate.

If able, I will post a photo or short video of the problem and solution.

You have two sensors on the engine that send a signal to the computer, speedo, and tach. If just one of these sensors goes bad your speedometer and tachometer can just stop working. Check if these sensors are blocked or if broken then replace.

Good Luck!
