Tl contact owns a 2004 chevrolet classic. The contact stated that the defogger has stopped working. When trying to clear the interior windshield glass, the exterior windshield fogs up very quickly. The failure occurs during different types of driving conditions.
Even though I have had the entire fuel pump assembly replaced and the in dash gauges checked, it will not register past 1/4 tank. After driving approximately 150 miles the gauge will suddenly drop, the low fuel light will come on. After turning the car off and on, it will again read 1/4 tank even when full.
How do you explain that and that still does not fix the ignition switch it is a big problem because now the car will not start I have called gm before and they say there is no recall.
Brake lines rusted through causing complete brake failure. All the lines(4) run very close together underneeth the air filter box. By running the lines this close together it allows moistures to be held in the tiny gaps between the lines, therby cuasing accelerated rusting and corrosion.
When we came back out, the car wouldn't start. It would turn over but wouldn't fire up. After sitting in the blazing sun with my sick child for at least 30 minutes, a friend came to assist us. The fuel pump was kicking on, we cleaned the intake and changed the air filter with no luck.
In two incidents an open door of the rolling car caught person knocking them down, one incident just missed rolling over foot. In each case found that car was not in park with key removed. Have also had multiple incidents where key was removed but ignition remained on draining the cars battery each time.
We stop and waiting for red light, when the light turn to green, push the accelerator pedal, but the car not have any reaction. I turn off the car, and start again then the car can move.
