Q:     I’ve had a water leak that’s ending up in my driver’s side carpet on my 1999 Silverado, creating a puddle all over the driver’s side carpet. I’ve been told my different mechanics to fix my weather seals, windshield seals or windshield replacement if needed, fender, and vapor barrier on the door panel. Today I took off my driver side door panel and the vapor barrier was perfectly dry. I am letting the truck sit this next week to see if water comes in when it’s just raining, or when I am driving. After pulling up my carpet I saw a small wet spot underneath the brake pedal. I bought this truck to learn how to fix any problems myself, as I would love to learn instead of paying for someone else to fix it. I need to drive almost every day for college, so hoping to not have to send it a shop and just work on it when home.

Any suggestions are greatly appreciated.

A:     I experienced a situation where I was getting moisture build up under the rubber mat and carpet on the driver side of my 03 Silverado. It had no odor like anti freeze so it wasn’t a heater hose leaking so I narrowed it down to plain water of some sort, but where from and how is it getting in?? My carpet and mat would be wet on non rainy days so that really threw me for a curve. I finally narrowed it down to the AC Condenser. The condenser has a plastic sealed housing around it that also serves as a catch-pan for condensation build up. Attached to the bottom of that pan is a rubber tube that leads out to the firewall of the truck to drain. Turns out, I had so much crud or sludge built up (decades worth) in that catch pan that the drain tube got clogged leading to overflow and ultimately leaking water from the top of the catch pan that clipped to the condenser housing. Since then I’ve been high and dry!…well just dry anyway. The overflow was what was making the floor board wet.

Q:     Both of the low beams in my 2012 Malibu burned out at the same time. I replaced them and still no low beams. High Beams and running lights/turn signals work. Ideas? Checked both fuses for r/l low beams and the relay as well as the fuse/relay for the DRL are all good.

Aaron Scott

A:     Both low beams are powered by a low beam relay that is turned on by the bcm.

If you have no power to both low beam fuses … move back to the low beam relay. Turn the headlight switch on and off … the low beam relay should click. If not, swap the relay with another relay in the fuse box.

If still no good … remove the relay … the relay socket should have 4 terminal pins … 2 pins should have battery voltage at all times. 1 pin goes to the bulbs, the remaining pin goes to the bcm. The bcm pin provides ground to close the low beam relay. If it’s not supplying ground the relay won’t close. If providing ground to the bcm pin makes the headlights work …. either the bcm is bad or the low beam switch input to the bcm is bad.

Q:     How do I replace the transmission filter on my 1986 Chevrolet Caprice station wagon 305? The transmission is having a hard time shifting. I want to replace the filter myself, how do I go about doing it?

Michael

A:     Take the trans oil pan off, Have an oil catching pan under it. Change the filter, replace the gasket and oil pan, Then add new oil, if you are unsure about this procedure I’d recommend getting transmission services.

You should also go to your local parts store and purchase yourself a Haynes Manual for your specific vehicle. It retails for about $15. It has colored illustrations and complete information on how to completely rebuild your vehicle from top to bottom.

Now if it has been a long time since the fluid has been changed you may do more harm than good. The old fluid in there is thick and gunked up which actually helps the worn out bands.

Removing the thick fluid and replacing it with clean thin fluid will more than likely cause the transmission to go out for good. Transmission fluid should be changed about every 25,000-30,000 miles.
