The blazer, keeping it, beginning to restore, need some help.

Hiya, you have a beautiful Blazer. The temp sender is a green wire in your under hood harness. If the gauge reads extremely "High" it isn't connecting, meaning there is a short causing a ground somewhere. I would also remove the plug from your cluster and clean your contacts that come into contact with the printed circuit. On the fuel gauge be very-very careful. Make sure your tan wire from the fuel sending unit is plugged ONLY into the "fuel" connection on your fuse block. Do not put 12 volt DC power to your sending unit, it will catch fire and you could explode your Blazer. If it is, then you have a bad ground on the sending unit. Be prepared to drop your tank and replace the sending unit. Door channel felts can be purchased from LMC or Wes in Olympia Washington. I use a sharp/wide screwdriver to remove the window channel on the vent side. Those are riveted in and use trim adhesive to glue the new ones back in. The rear door side just pulls out after removing the small screw in the rubber at the end of the window channel. Your dad gave you something special: a 72 K5 CST with a external spare tire mount. Have fun with it.
