I just started noticing a weird sound when I'm shifting gears. It almost sounds like a fan blade hitting something when the RPMs are coming down. It doesnt do it when accelerating, only when the the RPMs come down suddenly (pushing in the clutch.) And its only lasts for a brief second but it does it every time I shift. Any ideas? Thanks

  They are more than decent and about to go out of production I'm hearing as they are in direct competition to some of the other 'names' within the Goodyear brand. They only annoying trait they have is not uncommon to many brands. If let to sit for weeks they take a set and feel out of balance for a few miles until they return to normal. My mega-dollar Pirelli Scorpions did the same thing. Driven every day you never notice. Starfire Solarus HT is what is on the Pickup. Speed rating T. Dizzy is at the shop and I don't remember which is on that one.

  Kenwood Excelon KFC-XP6902C Excelon Series 6"x9" component speaker system designed for select Chevrolet, Dodge, GMC, and Toyota vehicles at Crutchfield This set of Kenwood 6x9 components is just what you need. They come with any and every bracket, speaker and foam needed. They sounded great to me when I used the stock system. After I went all out and added a new head unit, amp they sounded even better. Simple install.

  Thanks for the responses. It may well be related to the key fob unlock function - the truck unlocks itself driving down the road as well (neglected to mention in first post ;o((. I have a real basic model doesn't have the auto window rolldown function so nothing comes up on "settings" (or anywhere else I can find). Holding the unlock button didn't make window roll down happen either. I guess the electronics might still be installed but disabled for my base line truck. I put the fuse back in so all windows work from the driver side, now but the lock function doesn't work at all on driver side. Unlock does work from drivers' side and lock does work from passenger side. I am not at same location as other key fob, so we'll just work with key only for now. The fob I've been using has been relocated to away from truck and that seems to keep windows up. A new fob is expensive, isn't it?
