Posted August 25, 2010

I have a 2002 Silverado 1500, 2WD. The heater position control only works on defrost. I can move the dial to floor, panel, etc., but it stays on the defrost setting only. I can change the temperature O.K., the A/C works, and the fan speed works,...just can't change the flow position.

Any suggestions as to what the problem may be, and what the solution is?

Thanks...

Pud

  Of course that would be false. You could have had one welded into your stock pan if you could find someone who did TIG welding.
- Front hitch/ winch mount build
  
  By HoosierZ · Posted 5 hours ago
  
  I was recently given a cheap winch for my trailer and I’m going to build a front receiver hitch so that I can use it on my truck also. It is a 13,500lb Sinoking winch with synthetic rope and wireless remote. It is mounted on a Badland hitch mount. The lower plastic was removed from my truck several years ago when I built a custom tube framed skid plate for it. The hitch will be tucked up close to the bumper and hopefully I can add a 2” square tube to the back of the skid plate to fit it into the hitch to hide the hitch when it’s not being used. More pictures to come.
- Measuring Transmission Temperature for Setting Fluid Level - 6L90

  Hi All, I am curious whether using the dashboard display for transmission fluid temperature is considered acceptable when setting the transmission fluid level after a pan drop, filter replacement, and fill. I have a 2021 gas/6L90. Thanks

  Every place on the hi-way is up , lowest is the truck stop, $3.93/ 87, the others haven't broken the $4 barrier yet but getting damned close. Lowest diesel $5.73. I haven't checked local yet but I bet they are over the $4 mark. I've been shopping for a type C motorhome and trying not to buy a Ford, found a couple diesels but the price of fuel is scary

  Honestly? I've still been keeping it at about 3000mi. A hair over maybe.
