Hey, My 1991 GMC Jimmy seems to have an electrical problem. My motor and everything works but when it comes to the interior electical it gets realy messed up. even though my truck is totally off my delco radio will come on for a few seconds if the volume button is pushed but goes off. the radio shouldn't do that because it has a whole other power button. The radio won't even work. the dome lights all act weired when the dome light switch is turned and a bunch of other service lights won't go off. The gas gauge won't work either. Do you know what is wrong? please reply.I love this truck.

P0440 = Evaporative Emission Control System Malfunction.
Start by checking the gas cap.

I've checked, the battery and starter.
The problem started about a week ago, when the truck would turn over and die (spudder). Also, during this summer my gas tank started to leak, so I've been only putting $20 at a time.
Anyways, now I turn the key, everything powers up, goto start her up and nothing? not even a ticking from the starter.
I really don't want to give it the garage, cause they already said its big $$ to fix it,(I had only told the symptoms) and in the same sentence "we'll give you $500 for it"

The switch you are talking about is covered under warranty by an existing recall. Check with your dealer to see if it's covered.

I'm new, also. My '02 ZR2 Blazer is having A/C and heat problems. No matter what temperture/setting I used, the A/C flowed instead of the heat. I've done a flush and fill with DexCool, (because the shop said it's best to keep using it - it just has to be changed every 30,000 miles. I even told them about the horror stories and how GM knows it's a problem. They said "No problem, just come back in a few months and we'll make sure nothing is wrong." I'm still worried about it.) I've had the dash pulled off and the heater door unjammed (a 6-hour job... if the mechanic knows how!), the heater core flushed, the A/C temporarily disconnected, and finally the heat works again.
Any suggestions on what else to check, to get the A/C and heat to switch back and forth?

Look under the dash on the drivers side. There is a bolt above the emergency brake bracket that provides a ground path to the dash. There are one or two ground wires that are grounded to the chassis at this grounding point. The bolt can work it's way loose and cause all sorts of the problems you experience. You will likely find that the rest of the gauges (including the gas gauge) do not provide stable readings either. Simply tighten the bolt (if I remember it's a 7/16" wrench) and the problem should dissappear--it did on mine. Good luck! Dennis

What if I told you guys in this forum that I have a simple answer to fix your problem? Well I do. When I had this problem I had to pull over the side of the road because I thought a helicopter was over my truck. I too had found out that if I hit my 4wd button that the noise went away. The answer????? A 3 way vacuum switch on your transfer case above your encoder motor. To test:if your not sure find the vacuum line coming from vacuum diaphram under the battery and follow it until it comes to a tee. Unplug any vacuum hose in the tee and take it for a drive. there will be no howling. Now plug the tee vacuum back in and replace the vacumm switch on the tranfer case(10 minutes). There is a steel ball in the switch that corrodes in place.
