While the Nitro shares some typical crossover features with competitors like the Equinox and even Dodge’s own Journey and Jeep Liberty, what it doesn’t share is typical conservative styling. This boxy beauty (or...
Hi there. Check the blend doors to the heater system. The doors could have a leak with the weather stripping. Then check the air ducting in the dash up by the heater blower motor and see if there is a...
There are several possible causes when it comes to an overheating issue. A water pump or thermostat are definite possibilities, but there are still quite a few other possibilities. An air pocket in the cooling system, a clogged radiator, or...
Hi there. Remove the battery cables and wait 30 seconds and then hook the cables back up. This will clear the security system in the vehicle to reset it. The alarm should shut off and stay off. Then take the...
Hi - the sudden nature of this failure would suggest a fuse or other electrical link, but you have checked the obvious. Further diagnosis is needed to determine which component in the electrical power chain has failed - switch, electrical...
Hi there. Check the brake light switch on the brake pedal. The switch may be shorting out with the headlight switch wires and causing the headlight power to engage the brake lights. Fix any wiring in the vehicle that may...
Hello, thank you for writing in. The thermostat is located under the coolant reservoir at the front of the vehicle. There are diagrams available in the service manual. To start the process you need to access the thermostat. This is...
Hi there: The transmission speed sensor is connected to the transmission on most Dodge cars, including the 2007 Dodge Nitro. This video is a good one to show you how to replace the input speed sensor. If you review this...
Hi There, This is a sign of a faulty blower motor resistor. Blower motor resistors are resistors which are used to control the fan speed of automotive blowers. The fan speed can be changed either by switching the blower resistor...
Hello there. It's difficult for us to give you an accurate assessment on what might be causing your AC issues on the Dodge Nitro since we're not sure what you may have removed in order to replace the blower motor....
Hello, thank you for writing in. When the vehicle fails to shut off after turning the key in the ignition, the ignition or the alternator are not "turning off". Although it is a bit more technical than that, these are...
Once the car is completely cool, check the coolant level in the radiator. If low, that will cause overheating. If it is low, you might have a leak that should be diagnosed. If the level of coolant is correct and...
Hi there. Typically when this occurs it is because there is a cooling system issue with the vehicle. It can be an issue with the coolant being low due to a leak or it can be caused by an issue...
If the vehicle transmission has entered limp mode and the engine is really misfiring, these faults have to be diagnosed separately. The engine misfiring should be dealt with first. Typically, the engine is scoped to look at secondary firing patterns...
Hi there. Most of the time when this occurs randomly like this it is because there is a problem with one of the wheel speed sensors. I usually start by checking the tires first. If one of the tires is...
Hi There, It sounds like you may have a faulty blend door actuator. Inside your vehicle's vent system, there are small doors that open and close to change the flow of air running through the system. These doors are operated...
Hi there. If the blend door actuator was not damaged, the only other item I could think of would be an electrical fault such as a damaged relay or fuse to the system. It's also possible that the switch itself...
There are many causes of hard starting but illustrative ones are a faulty engine coolant temperature switch (sensor), air induction system problems such as a faulty idle air control valve, worn spark plugs, inadequate fuel delivery or pressure (clogged fuel...
This is an interference engine, so if the timing belt breaks the valves can hit the top of the pistons. The timing belt in this application should be changed every 75,000 miles or so, so if it has never been...
Hi there. In most cases when this occurs, it'd due to a restriction of fuel pressure either caused by clogged fuel injectors, a throttle body that is worn out or dirty or mass air flow sensor that is causing problems...
Hi there - based on the Owners Manual (Pg. 351-353), the 3.7 L engine requires 87 octane, and the 4.0 L engine requires 89 octane. The manual also cautions against using higher octane fuel than required, as this provides no...
