I have a 99 Grand Prix SE. Recently I had a blower resistor card replaced because my hvac blower worked only from the #3 setting and up. A few weeks later I noticed that when starting my car my daytime running lights would take about 10 seconds to kick on. They used to come on right when I turned the ignition key. Most recently my climate control panel has been acting up on me. When I start my car and put the heat (or a/c) on my drl's cut off and everything losses power. No heat, no a/c. Not even rear window defogger. When I turn the hvac off my drl's come back on. My mechanic is at a total loss. What makes it worse is that it doesn't happen all the time which makes it even more difficult for my mechanic to find the problem. Any suggestions would be greatly appreciated!
Thanks,
Marty
Looking for any ideas on where to go next???
Thanks,

Help
I've read a few posts regarding the hiss problems. I bought my '06 GT. at the end of January and noticed the hiss early on. I have the Monsoon stereo with XM, as well as OnStar. I know the hiss is some kind of electrical interference problem. As soon as all of the dashboard lights and interior lights go off, so does the hiss. I waited until my first visit to the service department at 3000 miles to inquire about it. The service manager basically blew me off when I told him about it, since he couldn't hear it.
Well, I was back in the service department on May 27th for my 6000 mile oil change, etc. This time I had the service advisor (not the manager) sticks his ear up to a speaker and of course he could hear the hiss.
The problem was diagnosed to be an amplifier that failed internally. So, I waited for the part to come in and had my car in the shop all day yesterday (apparently replacing the amplifier required the removal of the back seats).
I drive away after the "repair" and realize that the hiss is still there! :mad: If anything it's worse now. I can try to ignore it, but it's so annoying! It is constant noise from the speakers.
Has anyone had any success with getting their hiss resolved? I'm wondering what I should do now.
Thanks,
Thinking it was a clogged fuel filter, I changed it out. Didnt help. Its seems to die out at 3-4k rpm if I hit the gas, but has died on lower rpm... (BTW I can hear the fuel pump engage when key is turned)
Took it to a shop, and they said the Crankshaft Position Sensor is bad and the Electronic Igination Module is failing.
Car has 145k miles. Was wondering if others have had this problem? No check engine light. Not that I dont truse the shop, but other people with the problem and fix would be helpful. Thanks.
put your wipers in the upright position, Open the hood. Remove the plastic wiper fluid hose off the clips. remove the rubber gasket hood seal. there is a plastic cowling that covers the lower passenger side of the windshield. this is removed when you change the air filter for the passenger compartment. the trim screws are 2 piece clips. pull out the center (heads looks like a nail, and then pull out the outer section. There should be a 2 foot section of rubber gasket that is on the sheetmetal that the windshield rests on. This is supposed to deflect the water. Mine had fallen off, letting water run right into the fan box. GM sells a new colwing for this that replaces the gasket, and stops the water from hitting the airbox. It is not covered under warranty, but it's less than $4.00. (yes, a gm part for less than 4 bucks). This is easy to replace and can be done in 5 minutes.
Also the low fuel light comes on whenever it likes, full or empty.
Also the rear leaf spring Moans on bumps.
DS PW switch is 'opposite' of what is normal.Wiring ok
Dash lights/radio lights intermittent, when they go off I hear a click under the dash.
I like the car still, but help!
I diagnosed the problem and repaired it myself, with a bead of RTV on the underside of the plastic trim.
They also told me that the linkage could not be worn out, after I diagnosed it. They did end up replacing the worn linkage!
Here is my crazy question.
Could the supercharger have anything to do with that?
The supercharger belt broke and I left it off.
I know the fan is good, I know the relay is good.
