I no longer have feeling in my feet. My heater (2002 Sonoma) works fine except the knob setting to the lower foot area seems to not divert warm air to your feet. In fact its disgustingly COLD. My legs and feet turn numb on a 20 minute ride to work. There is lots of hot air, you just can not get any flow to the foot area. I had this problem a few years ago that I diagnosed as the door inside the duct to have broken at the axle/shaft: where it connects to the actuator cable up under the dash. The actuator is pneumatic and it worked well, just moving only the broken small diameter plastic shaft. It was reparied under warranty (Over $400 charge to replace a junky-cheap plastic part that costs a few bucks) My question is does any body know what is involved with the repair ? It sure seems like you need to disassemble half the dash to get at the duct work. Secondly, I dont want to put the same doomed-to-fail part back in there. I am likely to keep the truck for a while and I want only to fix this once. I am thinking once I get it apart I will figure out a way to reinforce the break point but maybe someone has already soved the problem ? Thanks

How would a person get to and replace a brake bulb on a 2001 Concord. Thank you in advance
