When i turn the power on the lights come on ( on top ) then a light comes on the bottom (the light looks like a wrench ) then all the lights go out and the chair won't move.

There is something caught in bottom of it!to clear it you need a Allen wrench on the bottom of disposal.

Do you mean 2006 GMC Envoy?
Top left- car with squiggly tire tracks and a wrench- that means something is wrong with your Stabilitrak (traction control) system. Top right- triangle around the car with squiggly tire tracks- this light comes on when the light on the top left comes on. It also means something is wrong with the Stabilitrak system. Bottom left- Antilock Brake System warning light- This means there is a fault in the antilock brake system. Considering that the stabilitrak control is part of the antilock brake system, it looks like there may be a common problem affecting both systems. You need to use a scan tool to access the chassis control system and read the diagnostic codes. There are definitely Diagnostic Trouble Codes stored when these lights are on. The code does not tell you what part to replace, but rather gives you a direction to go in diagnosing the cause of the problem.

Let it power on. If it plays the normal windows music then look very carefully at the screen. You may need a flash light. If you see a faint image then your inverter board or back light have burnt out. It will a small board 1 x 2 inches usually and have a small wire coming from the power supply and one going to the bottom or top of the screen.

the starter is located at the rear of the engine
diss connect the pos side of the battery
jack up the car and use jack stands for safety

with a light of flash light look up behind the motor from under the car
you will need a wrench size #12 metric for wire the other wire is just a
clip on

you will need a #14 wrench or socket for the bottom starter bolt

from the top of the engine drivers side look down to the starter bolt
you will need a # 14 wrenck to loosen and a socket #14 with a long extension
move wire harness out of you way just a little so you can get the socket on it have somone help you with this have your helper hold the starter from the bottom while you take out the bolt

when the starter is loose it will come out of that mess if you move to the right and pull the plastic guard to the side a little

try using a 1/4 allen wrench and manually turning the blades. there is usually a hole in the very bottom (on the outside, under the sink) of the unit where you can use the allen wrench to turn the blades. make sure the unit power is off before you do this. sounds like something is binding the blades.

Probably some bad capacitors in the power supply or inverter/RF circuitry for the back-lights.
look for electrolytics with the top bubbled up on them, or bulging plug at the bottom or leaking electrolyte...these caps all need to be replaced.

You may have a problem with the turn signal switch, as power comes out of that switch to power the brake lights, the high mounted brake light does not go through that switch.

You will need a OBD2 code reader, that will give you a "trouble code" then that will tell you what direction to look in, for the problem.

Check for power out of brake light switch by brake pedal. Of its faulty , the 3rd brake light will still work. Hope this helps
