Q: Air conditioner squeaks and only works on high

The service engine light (https://www.yourmechanic.com/services/check-engine-light-is-on-inspection) would have to be scanned to find the cause of it being on. The overheating can be caused by the thermostat stuck or the fan control system problem. Since the engine overheated the loss of...

The vehicle will have to have the throttle body (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-throttle-body) and idle air control valve (https://www.yourmechanic.com/article/how-to-clean-an-idle-air-control-valve-by-joyce-morse) checked to see if it needs to be cleaned. Also, the engine will need to be checked for any vacuum leaks (https://www.yourmechanic.com/article/is-it-safe-to-drive-with-a-vacuum-leak) when the...

Hello! I believe the problem will be within your ignition key lock cylinder (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-ignition-lock-cylinder).

Something may not be well connected causing an intermittent misfire. The Check Engine Light comes on steady...

Hello - I suspect that either the flange joint after the converter has a defect (https://www.yourmechanic.com/question/-i-have-replaced-my-exhaust-manifold-a-half-dozen-times-why-is-this-happening-by-stephen-k) that continues to leak, despite new gaskets, or the muffler is stopped up, increasing exhaust pressure on that joint. I recommend an exhaust system...

What you are describing may be a result of a faulty speed sensor, potentially low transmission fluid (https://www.yourmechanic.com/services/transmission-fluid-service) or a even a faulty transmission control solenoid. As your vehicle travels down the road, the computer analyzes data being sent by...

Hi - the # of miles between oil and filter changes (https://www.yourmechanic.com/article/why-do-cars-have-different-oil-change-intervals) is perhaps the 2nd longest running discussion since someone said "My car is faster than your car!". Driving conditions: clean air/dusty, freeway/city stop-and-go, long drives vs 3 minute...

What you are describing sounds like a wheel bearing (https://www.yourmechanic.com/services/wheel-bearings-replacement) that may be starting to fail. A wheel bearing will usually fail due to pitting or small damage on the surface of the rollers or the bearing race. Both the...
