It says to put in auto,but that don't work
Okay so my brake lights aren't coming on with my led taillights. But they do come on with my lights set to auto however they do not with my lights fully on or with marker lights on... if I also changed the bulbs all to incandescent and everything works as it should. So what the heck is up with that? Lol also they have worked in the past up until now which tells me the led taillight might have faulted?
It sounds like aluminum cans in a larger can banging around. Even when the car is idling the noise persists. It is not usually there when you first start the car.
As of this morning the heater isn't blowing. Yesterday I drove for 20 minutes before it decided to come on. And that was after allowing it to warm up for 10-15 minutes. But today it didn't blow at all. Should I still try to wiggle the wire or does this sound like something else
Turn it all the way up on high and 90 and I feel heat coming through the vents but no blowing at all
In the morning, I drove to work with no problems and the check engine light was not on. After an eight hour shift, I started the truck and noticed the check engine light was on. I had it diagnosed at Advanced Auto as a PO442 code. If I change the gas cap and the check engine light is on, where can I look in the engine to check the carbon filter or hoses?
the 30 amp fuse controls the driver seat and both passenger windows and seat. when i replace the fuse it blows out after 5 minutes. the fuse also controls the heated seat on the driver side
radio indicator will not light up. The service man at FH Dailey informed me I need a new radio. Please verify that it is ture.
