Some time back (years) I posted about the interior of my cab getting wet. It wasn't noticeable unless you placed your hand on the passenger side carpet, then you'd feel a slight moisture. It was not the ac evap tube as many on here posted. This past winter I drove through one heck of a rain storm and both sides were soaking wet. Today it was nice and warm and I was motivated. I removed the complete interior. Didn't really see any large neon sign saying looky here. I did find however a few telltale marks coming from each lower corner of the rear window gasket. I do have the sliding rear window, not the solid one. The drivers side rear-side window may have a leak to it as well. I squeezed auto sealant up into both corners, under the gasket. Tomorrow with a water hose or Wed when it's supposed to rain I'll do a water check. I did put the drivers seat back in it for use. I mostly ride my bikes so being without a truck isn't a big deal.
Wish I'd been motivated long ago to do this.
While the carpet is out, I laid the water hose, soap, and scrub brush to it. Scrubbed the dickens out of it. Looks the cleanest it's ever been. Can't believe how much crud came out of the carpet on the drivers side, especially where my left foot rests. Can't figure that one out. Brown junk poured out for 5 minutes as I hit it with the hose. There sure isn't much sound deadening in the cab either. There are two small pieces on both sides in the rear that lay down in the pocket. created by the arm rests.
I may see if there is a asphalt sheet or something I can lay down in there and mold it with a heat gun for even more damping. Truck is pretty quiet as it is.
This truck came with the Infinity system. Front and rear speakers have the amp built onto the back of each speaker. I've read on this forum years ago, that the amps were a separate unit under the dash. Not on mine.
The truck is 11 years old, has over 200k miles and is still going strong. I did rebuild the tranny at 122k. Most of the front end has been rebuilt over time as its worn out. I probably should have done it all at once. The TRW track bar is still holding up well. The truck is starting to show some signs of wear. Phooey! Can't beat it though. It's long been paid off and is still making the tires go round and round.
