2005 GMC Sierra - Page 3 - Answered Questions & Fixed issues

Sounds like the blower control module. Alo inpect the multi wire plug,they sometimes get damaged from the heat. The module and plug should be in the immediate vicinity of the blower motor,generally behind or below the glove box

Hey im not 100% sure this is it but it sound like it.. I had this happen to me. their is something in the anti theft system that enables the car to start.. I found a module that you can install yourself.. read over the page and see what you think.. Your truck is on the list for having this issue.. I hope it help

Are there any lights lit on your dash??? It could possibly be the theft system.. I had it happen to me in my buick.. I found a site and it has the lit of cars that it might happen to. With what you described this could be it. check it out and read through it.. Its a very easy fix that you can do yourself!! I hope it helps let me know if u have any questions

Are any light's lite on dash ? check engine ? There are a lot of electronic components on these vehicles. Fuel Injector Control Module for one. Crank sensors, fuel rail pressure sensor , engine computer (ECM) and you should have a professional grade scan tool to work on these vehicles . You could look on YouTube, there are a lot of guys that post auto repair videos there, even ones on diesel's with no start problems.

Usually when this happens you will have a loose contact (earth wire) and it may be hard to find. Try removing the lower cover around the steering column and, with lights on, reach up behind the instrument cluster and wiggle the wires.

It sounds like you have an earth problem (Negative or Black wire on most vehicles) so try tightening the - pole on the battery and make sure it is clean.Also check all earthing points on the vehicle to make sure they are tight.

coil pac's or pac could be shorting out .. does it start back up after it cools down ?? take em in and have em tested...

you lost them????? LOL ok , my guess is you want to study them,? the FSM covers that totally, buy the book? or if in USA< log in to alldata.com and read it there? please give hint as to the why?

take it to any gm dealer they can check it and fix it if it has not been done yet

go to autozone.com and check out the repair manual there to much to post

no it does not mean if you look at a fuse that it is good you have to use a voltage tester across the fuse . If the power is there follow the wirring diagram there are relays because the two seat do not work you got a commun connection that is not feed or broken it is always that way 1 check if you got power 2 check down the line until you find the broken connection. I hope that will help you. PS patience

The whole dash panel is one unit. You will need to check the wiring going to the dash panel. Check the connectors and make sure they are snug on the spades. The whole unit may have o be replaced. You can find it at autopartswharehouse.com for an unbelievably low price.

You can not always tell if the fuse is good, just by looking at it you have to test it after that you have to follow the steps in your manual .Like power to the relay ,the connections

you have a problem with the heater/a/c controls there obviouly stuck on a/c you will need to strip out the control panel to see why the direction/vent , hot/cold , fan speed controls are not working , before doing this have you checked the fuses as there may be a seperate fuse for the control panel ,if this all checks out take to an a/c specialist as you dont want to mess around with a/c gasses etc

you need to change the point distributor , but before that check the cable from coil to your distributor .

try this:remove the negative cable at battery,wait 5 minutes then plug it back!...what's up?

check the oxgen sensor

If the gauge stays at 3/4 my guess would be the sending unit in the tank is stuck in place.

it is your actuators going bad. need to replace the one for the side giving you problems

did you possibly disconnect the wiring from the back of the radio..check the fuse for it.. see if it broke(burnt out).is the key on?
