When people change motors it is a common problem to forget that each engine requires it's own wiring harness for it to use all the relevant sensors. It is not always possible just to put the plugs together and expect everything to work ok as different pins do different things . LIke do not supply power to fuel pumps.

SOURCE: no power to 6.2 diesel fuel pump

Try finding a good ground, first, if you're still not getting voltage, check the fuel pump relay under the hood.

SOURCE: 2001 chevy silverado 2500 hd, 6.0, replaced fuel

If you are sure the fuel pump relay is working, check continuity from the pump to the relay socket. These wires love to corrode. When you turn your ignition on, the fuel pump will only run for a couple seconds before it shuts off via the automatic shutdown relay. Make sure you are checking power within this window. The PCM (powertrain control module) is what completes the ground in order for the relay to send power to the pump. If the PCM does not recieve a signal from several sensors (mainly the Crank Sensor) it will not turn on the pump. You may want to check these sensors, is the check engine light on? You can scan it to see if any sensors have thrown a code. Be sure all applicable fuses are ok, the PCM may have its own fuse, check that even if the fuel pump fuse is ok. Your Truck may also have an inertia switch for the fuel pump which shuts it off during an accident. Check that as well.

Remove heater ac air posion moter on 2008 chev pickup


I think the part is called the blend door actuator.
1.You have to remove the plastic cover on passenger side. Motor is located over the transmission hump.
2. Remove wiring harness plug.
3. Remove 3 hex head screws.
You need a small 1/4 socket set.

Why doesn't ac blower work on number 5 setting? it is a chevy hd gas engine


Most likely the blower motor resistor. It's mounted next to the blower motor under the dash. Also check the 7 wire plug going to it, GM had a problem with that plug, and the wiring getting hot and melting. The plug is $68.00 from the dealership. One of my customer's car had the same problem.

2006 silverado 5 speed heat, the high speed is not working. I do have the 4 lower speeds


The switch, high blower speed relay or the wire harness at the blower motor has gone bad. The highest setting 5 has no resistor, so the blower runs on high but the high current flow ends up burning up the switch's contact on that setting or the relay and may be the resistor wire harness at the blower motor has gone bad. Common would be the switch it self, if the switch is good. Then it's going to be the blower relay or wire leads at the speed resistor by the blower motor under the glove box by the passenger leg compartment. Keep me posted, be glad to help you get your Silverado running 100% again soon.

2006 Chevy Silverado. Blower motor harness and resistor is melted any idea of the part numb ers and a good place to purchase these besides a dealer? Thanks, Joe


If there is a Auto Zone around your area, you can buy the blower resistor for around $30.00 or Parts Source and they will have the step by step instructions for you to get the job done with common tools and they can also order you any wire harness you may need if damaged. Good luck and keep me posted.

Brake control hook up


off of your factory harness you will have a small brown wire and a small blue wire among the 5. Do not use the small brown wire, use the blue.
