Hello, thank you for writing in. The climate control utilizes something called "blend doors" to control where the air is being sent through the ducts. These blend doors are controlled by servomotors that open and shut them. Something has likely...
According to the AC Delco catalog, the OEM (original) pump used in the 2500 is A/C Delco part number 15909826. The OEM (original) pump used in the 2500HD is part number 15909827. Although there also "appears" to be a generic...
Depending on the conditions when the stalling occurs, this may be related to the various loads put on the motor which may indicate a faulty MAP sensor. The Manifold Absolute Pressure (MAP) sensor senses engine load and generates a signal...
Hello, thank you for writing in. It would seem for one reason or another that the charging system is having trouble keeping up with the vehicle. The alternator is the heart of the charging system and supplies all of the...
If you have a bad turbo lag then the turbo bearing may be going bad. The turbo is taking higher exhaust pressure to turn it fast enough to give good boost. Remove tub near turbo and wiggle turbo shaft and...
Hi there. The P0708 trouble code means that the Engine Control Module (ECM) has detected a malfunction with the transmission range sensor. A mechanic would begin the diagnosis of the P0708 trouble code by finding the manufacturer’s suggested procedure for...
Hello, thank you for writing in. Typically this is a sign that the vehicle is trying to tell you something. The first step is going to be scanning the vehicle for diagnostic codes to see if there is an issue...
Hi there. Sometimes a new compressor installation will not produce the desired level of cold unless the high pressure and low pressure hoses are also swapped, pressure checked for leaks and tuned after adding refrigerant. In other instances, components beyond...
Check to see if there are any stored diagnostic trouble codes. Be sure you have a fully charged battery that passes a load test. Confirm that the engine immobilizer system (security system) is not activated thus preventing the car from...
If it's a "new" motor, and the bearings are possibly dry (they shouldn't be, but you never know), you can pre-lube the motor by using a Pre-Lube Engine Oiler Tank. After ensuring there is oil throughout the motor, verify that...
If the coolant level was low due to a leak, such leaks can be found during a leak diagnostic with simple pressure testing. If the cooling system doesn't maintain pressure, and no external leak is visible, coolant could be leaking...
Check all of the battery ground cables to the car on the battery, engine, and chassis. There is a bad ground somewhere that is causing the ECM to not work properly. This would cause the fuel pump to not work...
Hi there. The power steering and brake system are not related mechanically. However, it is possible that prior to working on the power steering system, the ABS module was deactivated or an electrical connection was removed; which can cause the...
Hi there. As long as your transmission is a 4L60E, or a 4L80E, then the engines will bolts up to the same transmission. Most of the newer transmission have a replacement bell housing that can be swapped around with different...
Hi there. P0700 is set when the PCM detects a malfunction in the transmission control system. This malfunction causes the vehicle to set a Check Engine Light and trigger a failsafe mode. Once the failsafe mode is set it will...
Hello. We will be happy to assist you. There are are a few things that I recommend a technician inspect. Fuel should have been inside the filter once you removed it. A test must be done to see if the...
Hi there. Alert chimes are triggered by sensors located on doors, seat belts and other devices that alert a driver that something is either open or not properly secured. To determine why they are not working correctly, have a mechanic...
Hi there. Usually the reduced power light is caused by an engine component failure, like the throttle body, TPS or bad O2 sensors. It is very possible that the additional transmission fluid has created a trouble code that might have...
Hi there. Understanding what causes the transmission hot idle warning light is critical to diagnosing your problem. The Transmission Hot – Idle Engine message can be displayed when the transmission fluid is too hot, which prevents the transmission from cooling...
Hello, thank you for writing in. Unfortunately, there are a large number of components that can contribute to this issue. The first thing you will want to do, regardless of a check engine light being present or not, is to...
