Misfire on all cyl. Sometimes more sometimes less. all over the place
6 or 8 cyl ? Were you driving down the road when it happened ?Usually the ignition module is inside the dist and that fires the coil. The coil is either in the cap or mounted on the intake manifold.If the truck has over 100,000 miles the timing chain could be off. A timing light would tell you.
How do i replace the right side power window switch
You need to take off door pull. then unsnap door panel unscrew lock knob. Then slowly raise door panel unhooking it from handle that will still be sticking through. As soon as you have it unhooked from handle you should be able to tip it away far enough to get to switch on inside of panel. There should be harness clip to unplug from switch then unclip the switch. Not to hard just time consuming. Good luck

You have a serious short circuit in the instrument panel and if the fuse did not blow and if you didn't switch of the motor your car could have caught fire.You need an auto electrician to fix this problem. You maybe able to trace down the short circuit by looking for burnt electrical wiring etc. but you also need a wiring diagram to trace the wiring to replace the the damages wiring and any components.
My 1989 gmc sierra truck
I had a similar problem with mine. Turned out to be a bad ground connection in the tail ight assembly. There are steel tabs that spring out and contact the steel stamped out frame in the plastic around the bulb sockets. They were making a bad or no connection and were rusted. Bad design :( Anyway I used a very small wire wheel and removed the corrosion and soldered the connections. No more problems!

it should.......but a transmission shop will need to verfiy it. Get the trans pan off and check the condition, (excessive metal in th epan) and replace the filter while its out. Have a trans shop check it, you dont want to put in a bad trans.
1989 GMC SIERRA BRAKE LIGHT IN DASH STAYS ON
Check your emergency brake. Make sure it isn't partially pressed in. Try unplugging the switch to the emergency brake and see if the light goes out; if it does the switch is bad.
