An overcharge of either refrigerant oil or refrigerant can cause excessive system pressures. If the wrong refrigerant oil is installed that might contribute to excessive pressure. Check low side pressure. If low side pressure is too low, while high side...
Many electronic components get tempermental before they fail completely. And this might be the case with your voltage regulator. It may simply be that you need a new alternator. But before doing that, I would first check all the connections...
Hi there. If you are having problems with a reverse lights, it is possibly due to a reverse shift sensor or damaged electrical relay that powers the light. It's also possible that you have an exposed wire that's causing this...
Hi there. In most cases, the reduced power light and the battery terminal problem indicates two different issues. It's probably best to replace the battery and both cables to resolve the initial starting issue you've described. In regards to the...
Hi There, Generally, the check engine light comes on when something fairly serious is going on with the vehicle. This can happen for many different reasons such as a faulty mass air flow sensor, a faulty O2 sensor, a bad...
Hi there. If the code cleared, it's possible that the source of the code is actually the wiring harness attached to the speed sensor. If the light comes back on, you might want to have a professional mechanic come to...
Hi there. When a hydraulic clutch slips, it's due to one of two problems. Either the clutch pressure is not properly set or a leak exists within the hydraulic system. In order to correctly diagnose this problem, it is best...
Hi there. If you turn the key and nothing happens, it is more than likely that your ignition relay is damaged or the battery cables on the Silverado are worn out, contaminated or simply loose. It's probably best to have...
Hi There, This may suggest you could have a bad transmission shift solenoid or potentially a faulty transmission temperature sensor that may not be functioning correctly. Many newer automatic transmissions have temperature-sensors in them that, on a stone-cold start, restrict...
The problem sounds like the stop lamp fuse in the engine compartment fuse box 20 amp is blown. Check this fuse and also make sure it has power to it. If bad try replacing it and go from there. If...
It sounds like this may be a sign of a faulty blower motor. As you might know, these have electric motors in them that wear out over time and will begin to make squeaking or grinding noises as the bearings...
Hi there. If all the cylinders on the odd side of your engine are misfiring, you probably have a serious timing problem or distributor problem. To determine the precise source of this problem, it's best to have a professional mechanic...
This is often related to a malfunctioning door lock actuator, a blown fuse or a faulty power door lock switch. When you use the door lock switch in the car it sends a signal to a relay which then activates...
Hello, thank you for writing in. Considering the age of the vehicle, the transmission may need to be serviced. This would include a fluid and filter change. During that process it can be inspected for signs of wear and obvious...
Hello, thank you for writing in. It is possible the shifter cable or its related components are damaged. They are typically visible from the bottom of the transmission. It should not be hard to inspect that area if you can...
It sounds like you may have a faulty connection within the battery cables or potentially bad cable terminal ends. If the connection within the cable is faulty or the terminal end are bad, tightening down the cable ends would potentially...
There is a possibility that the gas is contaminated although of course the issue (the noise and the underlying mechanical cause) could have just coincidentally arose right at the time you bought gas. You might check with the station and...
Hello. It sounds like the issue you are having now has nothing to do with the rear end. It sounds like the transmission is failing. This is a typically symptom of a cracked sun shell. Depending on how the rear...
Hi there. Generally speaking, when the heater is blowing cool air and the engine overheats, it's caused by the same thing - a clogged or damaged heater core. The coolant from the motor once hot circulates through the heater core...
Hello there. It's quite possible that the torque converter could be wearing out. Usually when it begins to wear, it will slip quite a bit, causing a lack of acceleration. If you smell burned transmission fluid occasionally, it's like the...
