It's possible that your headlight switch is the source of the problems you're having; (especially if it's all headlights that are not working correctly). It's also possible that you may have an exposed wire somewhere creating a short in the...
Hi there. In most cases, a bad or malfunctioning heater is accompanied by an overheating problem. However, if you're temperature gauge is HOT and you've got white smoke blowing from the exhaust, this can be an indication of coolant inside...
Hi There, The air box resonator missing should not impact the running condition of your vehicle at all. If the air box had cracks in it, this may have caused excess air to be injected into the intake system which...
The first thing I would do is scan the vehicle for codes to determine if the TCM is still the issue. If codes for the TCM appear, depending on the code and the problem, you may be fine to drive...
Hi there. It's very difficult to estimate repair time without seeing the vehicle or how many ancillary components need to be removed in order to replace a damaged component. A distributor specifically can be time consuming to remove and correctly...
The problem is although the current draw over 45 minutes might be "low", your battery might be weak, meaning it could have a bad cell and a low reserve capacity. It doesn't take much to "drain" a weak battery. A...
In the majority of vehicles, engine idle speed is controlled by an idle control valve (ICV). The ICV valve can fail or a faulty or blown fuse in other electronically controlled systems can cause the IAC motor to malfunction, leading...
In today's modern vehicles, running a vehicle completely out of fuel can be damaging (if not catastrophic) to your vehicle's fuel pump. As you may know, the fuel pump relies on the fuel running through it in order to maintain...
If the fluid was 4-5 quarts low, that's a third of the total transmission fluid capacity. The transmission has probably been running very hot because of that, causing accelerated wear to the internals (clutches, etc). Check the dipstick for the...
It sounds like you have checked just about everything that controls the fans other than the fan power relay itself. As you may know the coolant fan relay turns the fans off and on by receiving information from the coolant...
This car does not have an inertia switch for the fuel pump. Since you were in an accident then your vehicle crash sensor system will need to be fixed and codes cleared for the fuel system to be activated using...
Hi there, Your vehicle starting for two seconds and stalling could be caused by several things. It could be an anti-theft system problem, if equipped. It could be an ignition system problem, ie; a faulty ignition module. The bypass circuit...
Hello. The symptoms you describe can commonly be caused by a vacuum leak or faulty idle air control valve. A vacuum leak may allow unmetered air into the engine, which may causing the idle to stay high when the transmission...
Engine misfires can be caused by many different problems, but there are a few suspects that occur more than others. Generally, misfires are caused by either a spark or fuel issue or in cases, a combination of both. Spark related...
Hello there, thank you for asking about your 2001 Chevrolet Silverado 2500HD. There is only one power source that can engage the starter relay and that would be the ignition switch. The ignition switch should not be able to stay...
Hi There, It sounds like you may have a worn or failing CV joint that. A CV (Constant Velocity) joint is a shaft that connects the transmission to the wheels, essentially transferring the power from the drive train directly to...
Hi there. There could be an electrical issue with the cluster panel on the dash causing the gauge to malfunction. For the fuel smell, there could be a vapor fuel line that is cracked under the vehicle or the purge...
It sounds like you may have potentially got some of the critical sensors wet, which can cause them to send erratic signals to the vehicle's computer system. For example, if a crankshaft position sensor gets wet or is otherwise unable...
Hi There, It sounds like you may have low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car's computer activates...
Hi there. It's possible that this is just a minor issue; like the door lock being stuck or slightly bent. If this is the case, the door lock or hinge might need to be replaced. It's also possible that something...
Hello. Thank you for writing in. When the vehicle sits for an extended period of time, the oil collects at the bottom of the engine due to gravity. This causes the engine and components in which the oil lubricates to...
It could be as simple as a valve cover gasket, or as complicated as a turbocharger. Because of the way the engine is oriented in your car, there are several types of oil leaks that can end up on the...
Code P0128 is engaged specifically when the engine itself does not get to operating temperature in a specified time period. The only things that can cause this problem is an issue with the thermostat, head temp sensor, and the coolant...
