I was surprised to find out that whenever I turn off the engine of my GMC G1500, the A/C blower continues to blow. I wonder how I can turn it off since it has been eating up my battery. I can't afford to have my battery discharged. I've been leaving it that way for two days now since I cannot find the time to bring it to the repair shop. What should I do to temporarily turn it off?
If you want to turn off your engine temporarily, open your hood and locate the engine compartment fuse box. You can use your manual to locate this box. Once you've opened the box, you need to remove the 40 amp blower motor fuse. This would help you stop the A/C blower in the meantime. You need to bring your vehicle to the repair shop to have this fixed immediately to keep your battery from getting discharged. This might also cause problems with your HVAC system when ignored.
I own a ten-year-old GMC G1500, and lately I've been having a hard time turning the engine over. It turns but it doesn't fire. I did everything I could, and I even replaced the battery with a new one and changed the fuel pump and distributor but to no avail. What's wrong with my vehicle?
Let's face it—your vehicle is not getting any younger. As a ten-year-old vehicle, it is inevitable that some, if not most, of its parts are already deteriorating. In your case, the engine doesn't turn over because of a problem with the crankshaft sensor. This sensor is located in the front timing cover, under the passenger side of the engine, and behind the crank pulley. The computer of your vehicle relies on a signal from the crankshaft sensor so that it could send a signal for the spark and injector control. Try to inspect the wirings connected to it. If the wirings are okay, then there is a high probability that the sensor has failed. You need to replace this with a new one immediately for your vehicle to turn over properly.
My dealer said I have a problem with my manual valve position switch. I told him that I will just fix it at home. When I got home, I cannot seem to remember where the switch is located. I also don't know if it is possible to have it fixed at home. Where can I find it?
The manual valve position switch of your vehicle is located at the valve body of the transmission. You can find it inside the transmission pan. This switch is responsible for monitoring the pressure from the various ports on the valve body and sending it back to the computer. It tells the computer which gear range the transmission is currently in. You can do the repair at home. All you need to do is drop the transmission pan and pull down the transmission filter. Next, you can remove the fluid pressure switch by removing the bolts. Replace it and make sure that you re-torque the bolts by 97 inch pounds.
