97 Suburban wont turn over and blower motor will not work and the gear indicator won't light up. I can jump at relay with key on and in starts right up but blower and gear indicator will not

lister for a clicking from the start motor you may need some to help you. if you or your friend hear the click on the starter motor then the motor and it does not turn the engine or goes crunch like its engaged but does not turn,It will need replacing or fixing, if no click this could be the starter relay or the ignition switch or you have a lose wire tot he relay.

Looks like the low pressure switch gets power from a 10amp ac fuse. Power then goes to the ac relay which is powered on by the ac heat controller on the dash. Power then goes thru the high pressure switch to the compressor. The ac relay is grounded to the body. Do you have power on the lite and dark green wires going into the relay and is it grounded ?

Hi Kevin it sounds to me like your solenoid that is attached to your starter motor needs replacing had this with a ford cortina mk 5

http://toolsnyou.com/ go to the link get the service and repair manual and solve the problem

I would check the starter for voltage first - there is a starter relay that is grounded by the PCM. If the ASD relay is faulty the pcm won't have power. You should have battery power to the starter and power on the solenoid when you turn the key to start.

Have you checked the automatic shut down relay ?
It powers the injectors from a 20amp fuse number 5.

does the motor crank when key is turned?If so check for a spark at the plugs.Get an auto electrician bypass your alarm

If the fuse is good,check to see if there is voltage to the blower motor,if there is,replace the blower motor.Sometimes,not always,if you bump the blower motor,it will start working,if this happens,then the blower motor is bad,if it does not,the fan switch could be bad,but the relay is usally near the blower motor.Testing it with a test light is the best way to test it,ground one end of the test light,the other end has a point on it.Use the piont of the test light to touch all the legs on the relay,with the key on,and the fan on high.The test light will light up,on almost all the legs,but it will also activate the relay when you touch the right leg of the relay,the relay needs to stay plugged up as you do this.If you can not access the legs of the relay,because of a skirt on the relay,push the point of the relay into the wire that you are testing,or into the plug,near the leg of the relay.The legs I am refuring to,are the prongs on the relay.If the relay clicks and turns the fan on,when you touch the right one,then the fan,and the relay are good,it will be the blower fan switch.Now if you already have high,blower fan,and the lower speeds are the problem,replace the blower resister,It is mounted right next to the blower motor,and has about 7 wires plugged into it.

Heater blower motor resister is bad, replace, located under dash above heater motor.

Today 11-12-08 my 2003 H2 Hummer would not start. Checked battery it ischarged. Cables tight. Tried to start with portable booster pak. No go. Tridto jump start with my wife's Suburban. Still no go.
When I turn the switch I hear a single click and that is it. No engine turning over. While trying to start with key the headlights go out. Out of ideas, Will take to Chevy garage in am. Will post solution.
