Is there any where i can get a diagram for a steering colum for a 1984 gmc sierra classic pickup it has tilt steering and colum is loaded cruise wipers ect. thank you if you are the person who helped me before thank you so much your inform. really helped my email is [email protected]

theyve had quite a few problems with the switch on steering wheel but also check for any trouble / pending codes will cause problem with remote start and cruise

This happened me on a saturn ended up having pull the colum and change the ignition

Sounds like your ignition/key tumbler is worn. A lot of times tumblers can get worn to the point that the keys will stop working or work sometimes. Usually the key goes bad first, since they tend to get the most abuse. It is not expensive to replace. I hope this helps.

if i turn my cruise control on the light comes on on the sterring wheel but it wont set

call the dealership they cand fax you a breakdown of the parts

is it a tilt whell and does it have the air bag in? if so the switch comes out after pull the steering wheel and horn assemby and air bag off. Boom.

Do you have ballast resistor on firewall by chance? ( 2"x 4" ceramic like block,usually held with 1 bolt in center)

CHECK THE TENSION OF THE POWER STEERING BELT

Tighten those four bolts making sure no wires are in the way or damaged where they come out of the cokumn right around the area of the column clap

>>>>FIRST disable the air bag system
You'll need to remove the upper and lower steering column covers.
Also all the trim under the drivers side, kneee bolster, etc...
The ignition switch has 2 screws holding it on.
Remove those screws and all related wiring harness.
Then the switch.
Here is the procedure from GM......

Place the multifunction lever in the center or the OFF position.
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

Disconnect the battery negative cable.
Disable the SIR system.
Remove the steering wheel inflator module.
Remove the horn plunger contact.
Remove the steering wheel.
Remove the tilt wheel lever.
Remove the ignition lock cylinder. Remove the upper steering column trim cover.
Couldnt find a diagram. Hope this helps.
