P0304 (https://www.yourmechanic.com/article/p0303-obd-ii-trouble-code-cylinder-3-misfire-detected-by-spencer-clayton) is a "trouble code". The diagnostic fee that you are probably referring to relates to a check engine light diagnostic (https://www.yourmechanic.com/services/check-engine-light-is-on-inspection). The cost component in the check engine light diagnostic involved in merely downloading the "code" is trivial...

That particular vehicle uses an electronic sensor to operate the speedometer. If your speedometer is not working, that may be a sign that there is a problem with the speedometer sensor or wiring. A problem with the speedometer circuit or...

The radiator fan operates on a fused circuit with high amperage relays to drive them. The fan motor itself is also a possible and common failure point. Have a mechanic trained in vehicle electronics inspect the radiator fan (https://www.yourmechanic.com/services/cooling-radiator-fan-motor-replacement) for...

Hello. From what you are describing, it sounds like the mass airflow (MAF) sensor is not working properly (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-mass-airflow-sensor). The mass airflow (MAF) sensor helps to regulate the air/fuel mixture and the idle of the car. When the mass airflow...

Installing a new engine will obviously solve the problems related to the timing belt damage (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-timing-belt). As for the question of more problems, this is not really something that can be guaranteed, although I would recommend checking into the warranty...

The tires that you bought are wider (by 0.79 inches) than the ones you had originally installed. However, if the larger tire size is listed in the tire catalog as a direct interchange for the original size, on your year,...

A leak of engine oil onto a hot engine component such as the exhaust manifold would cause a strong odor. Another possibility is a binding serpentine belt (riding over a seized pulley) and the belt is overheating and smoking. If...

Check to see if the drive belt is intact. If it isn't that would explain the loss of power steering, AC and the battery light. If the belt is intact, then something must be locked up, preventing the other parts...

You may have shorted out a fuse that goes to the radio wiring to the body computer. Try to disconnect all radio wires except to speakers and see if systems start working again. You may have wired into the computer...

You'd better just wait until it cools off so that you can look in the radiator. Filling the reservoir will not help in an overheating situation. It may take an hour or two for the engine to cool off enough,...

You should have all the tires checked for a bent rim. You can check this by having someone follow you while driving on the road. The other person can let you know if a problem is visually noticeable. Another alternative...

The window regulator in that door has broken. The window regulator uses a series of cables and pulleys to move the window up and down. Oftentimes, the pulleys, (which are made of plastic,) will break. When this happens, the cables...

Hi there. Typically when the AC compressor is cycling, it will draw more power from the engine, which might make an existing rough idling engine "feel" worse. This could be caused by fuel system components like mass air flow sensor,...

You might be looking at the air conditioner compressor. It has a clutch on it so that the belt can freewheel around it until the electronic controller turns it on. It might turn on and off a couple of times...

Hello. If you have one window that stopped working it is typically caused by a window motor or regulator. These typically need to be replaced together. I typically remove the door panel and check to see if there is power...

Hi Brett. Thanks for sending us your question today. The first thing I'd do is refer to Jeep's repair and service manaul, to determine if they recommend any specific tools or procedures for this job. The heater core coolant tubes...

It is not a good idea to keep your a/c lines open to the atmosphere or the system will get contaminated and the desiccant filter will continue to absorb moisture from the air and can explode and send material into...

It could be that the service reminder was affected by having the battery disconnected for a short time. These days, it is wise for a technician to hook up an alternative power source while changing the battery to prevent memory...

If coolant has to be added more than once per year, there is a leak. To find the leak that exists in your case, and get the required repair estimated, please request an engine cooling system leak diagnostic (https://www.yourmechanic.com/services/coolant-is-leaking-inspection) and...

Despite your commands (dash versus defrost, etc.), if air is only blowing out of the defrost vents, but not the central dash vents, that means the blower door system is malfunctioning. The cause could be electrical or mechanical in nature....
