Defrost intermittently working cold then hot and back to cold with noise like a blower or under the hood, It sounds like a compressor. A/c Compressor and defrost is related. I am not sure if it vacuum controlled or electronic controled
I figured out it was the thermostat. The upper house was cold, thus the thermostat was shut,, The noise that sounded like a blower,, was the fan on the truck. Turns out it is a very intelligent system , The truck has a brain, that when the thermostat is stuck and senses the truck engine is hot,,, it does all it can to put all efforts to cool the engine. Thus it increase fan speed to a very high speed and shuts down all demands to the cab,,. It shuts down the defrost to conserve energy and to protect the engine... a good thing... I learned a lot and I hope this helps the next person... I am used to old school V8's that you tune by ear. This was a real cool lesson, no pun intended :). I feel very good about the technology our cars have built in them. Mahalo,, Thank you
My car started making a strange noise, as if it were a template's bearing or damaged band, but we've removed this last one and nothing changed. We've also opened the car's distributor and replaced the oil pump which was softly damaged, but again nothing changed. We've checked it with a stethoscope and the noise seems to be coming from the bottom. There was no overheating nor an oil failure, any help to give me?
Thanks for your comment, Delores. I tell you that we've finally solved the problem when we took the engine out and found three damaged propellers. We've then changed them and luckily the car is now working properly.
My van's fans are suddenly turned on and the temperature's pressure gauge is disabled. On top of that, a script warns that there is an engine overheating. The thermostat and temperature sensor were replaced, it worked better for two months but the problem is now back. What might it be?
Do you know whether your new temperature sensor is a good quality one? Nowadays there are many of them out there that are cheaper but only last for some weeks, or in the best of the cases months. You should check this first of all.
While driving, suddenly 2 of the ventilations start giving off hot air and the other 2 cold. I then have to stop the car, turn off the engine and wait for 5-10 minutes until I can start it again working properly. It is not that often that this failure takes place but I would like to solve it. Thanks.
Old battery went completely dead, changed it and now I don't have any turn signal noise, door chime, and my radio isn't turning on. I checked every fuse possible and still nothing, any idea what could be the problem?
First, check if there's any loose connector near the battery or semething damaged. I dont´t know Silverado, but maybe there's a sort of BCM or electronic module that controls all you mention.
2004 chevy Silverado. 2500 6litre auto 4x4
Selector switch does not allow air or heat anywhere except the window defogger. Nothing on the dash vents or floor vents.
New truck blew injector at 2000 miles had some othe issues with the screen and A C now it's a bent push rod
Does GM not make a reliable truck any more had a FORD before should of stayed there
I have no headlights, dashboard lights, radio, no turn signals, hazards (flashers), the motor isn't shifting right and can't go over 45 mph it won't let me, the the speed odometer, gas, no power to windows but if I hold the brake pedal to the floor everything starts to work with warning lights on?
2007 Chevy Silverado will not turn over. Has a new battery, took the starter out and had it checked. Starter shows good. Vehicle has no alarm system or remote control system. No sure what the problem is or what else I could check
I remote started the truck, after 5 mins. I got into the drivers seat. And noticed there was a burnt plastic smell. Then the rear passenger side window exploded and shattered.
I had not even put the keys in the ignition.
This problem is mentioned many times online. This is a safety issue not a warranty. There is a recall on the flat window, with the same problem.
Every sense i switched out my stock radio my park assist wont work. When i pull codes it says i lost com with radio. I have called Kenwood and chevy dealer and they all can not help me.
You have to tap brakes truck shuts off but radio and other dash lights st@y on so have to undo battery when ready to start you have to first turn key switch on pull gear levér to nutruel then reconnected battery and crank then as long as you dont put into park youcan move gear lever
