Re: the turning signal works and then it doesnt
Sounds like the "Multifunction switch" has broken. The Multifunction switch is a one piece unit that mounts to the column, and is what the turn signal lever is part of. You'll have to replace the whole thing, as it sounds like something's broken internally. To service the switch involves removing the steering wheel, and possibly dropping the steering column to access the wiring connections. As a precautionary note, care and the proper tools must be used when dealing with the airbag and its components in the steering wheel. I hope this helps

Try replacing light bulbs and flasher which may correct the turn signals. Check all fuses, however as for the speedometer, the plastic clogs or wheels have run their course, If you intend to replace these, suggest you purchase a repair manual for your vehicle.
the flasher is right below the radio,under the dash .it take 3or4 screws to take off panel.both flashers are under there.one for your 4 ways,and one for your turn signal.if your four ways work you can fill the flasher to determin which is witch. mine the four ways was on the left,turn signal on the right.they are not in the back of glove box.ther is apanel there with three relays but not for your turn signal.thank u gm jim.u helped me find them.
Will your Center High-Mount Stop Light
(CHMSL) illuminate when you depress the brake pedal, but the lower/outer lights will not?
-- Do you have to hold the signal lever in a
certain spot to get the turn signals to flash?
-- Do you have to hold the signal lever in a
certain spot to get the lower/outer brake lights to illuminate?
-- Will the signals work in one direction,
but not the other?
If you answered yes to any of the preceeding
questions, your turn signal switch is likely malfunctioning.
**One more question before we continue: Is
the turn signal lever not "cancelling" (returning to the "off"
position) after you make a turn? If this is the case, you have a broken
Before you begin disassembly of your steering
column, verify the turn signal flasher is not malfunctioning. If your brake lights
work fine, but not the signals (either direction,) then it's likely the flasher is burnt
out. The flasher itself is located underneath the dash near where the steering
column passes through the firewall
You have a bad multifunction switch.It is not hard to replace just remove the bottom cover on steering column and top should raise up enough to get to the 2 screws holding the switch on.If you can not get enough clearance with top cover on then you will have to remove lock cylinder to get it off.Just turn key to on postion then look under the lock cylinder part of steering column and you will see a small hole.Stick a small screw driver or pic into the hole and push the pin then remove lock cylinder.
Did all these problems happen all at one time?? If so you may have a bad body ground. Try running a electrical wire from the (-) negative side of the battery to the body and see if this works. Be sure this wire is to a place with no paint as low voltage electricity will not flow through paint.
A). If not try replacing the turn signal flasher for the turn signal problem. This is usually the culprit and it's easiest and cheapest to replace. The turn signal flasher will be found under the driver side dash next to the hazard flasher. Turn the hazard flasher one to locate it. If you want try swapping the turn signal flasher with the hazard flasher to see if this fixes it. They are the same style flasher.
If this doesn't work you may a faulty turn signal switch or some wiring issues.
B). It could as simple as the head lights bulbs need to be replaced, it's rare but I have seen when both bulbs blew at or near the same time. If your able check the voltage at the head sockets.
C). Could be a bad blower motor or switch. I'm not sure if these models have a resistor block or not. The resister block controls the electrical current going to blower motor which controls the speed of the blower fan.
