I'm not a mechanic but these are the culprits that I've experienced: 1. If you turn off the AC and there is no more noise then: a. Your compressor belt may be loose. Check the tension of the belt near the AC compressor. If the belt seems loose a +/- 1/2 inch give then it's too loose. If the Belt is so tight you cant move it an 1/8th inch, too tight.. could damage pulley. b. The Compressor pulley might be bad. Have a mechanic check it. Compressor parts can go bad and they work hard in extreme hot states like Texas. If it's not a belt, I'd pay to have the compressor checked. If you dont then live with the sound and when the pulley dies, deal with it? :)
it could be your valves or your engine
Most common culprit is a slipping belt.
You have a broken vacuum hose under the hood that supplies the switch.
It depends on the nature of the noise.
Most likely it is coolant getting to hot and boiling over, car is most likely overheating. Check for fluid under car, and temperature gauge.
If the whistling noise is coming from under the hood its your belt, that's what's wrong with my Sequoia. If its not coming from under the hood its probably a crack in the seem of your window.
There is a baby under the hood.
anyone have the answer
It is inside the under hood fuse box.
What causes ticking, check engine light, and the check gauges sensor to come on in a 1999 Dodge Durango 5.2L SUV?
Something is wrong. Have a trusted mechanic check it out before you get stuck.
