I have the Superchip, would this play any roll in the operation of the high idle? I need to test my truck to see if it's activated.

Running 19.5s with 16ply. I think i could run over a box of screws and be fine.

Mopar thank you for the picture and this great site!

Thanks, i am going to verify my vacuum is good at the servos and does anyone know if i need to check vacuum at the selector? I also had leaves in mine. I put my hands up in where the blower motor is and its pretty dirty. So i will be pulling it apart and giving everything a good cleaning and im thinking of putting a new heater core and evaporator in while i have it apart. Since my dash is gone i do feel some air blowing around the center vents in the dash. Is there a seal on the casing that may have withered away? I have some foam like material that has blown out some of the vents.

I had some of my wonderful dash fall down in there could ot be possible it might have jammed something up? And i will check the selector and see what i can find there.

Does the floor vents go through the evaporator also because it works great in all blower speeds? I have a vacuum gauge i just purchased and im going to compare the vac between the hood and in side of cab.

The floor setting works great in all blower setting (low through high) but the defrost isnt the greatest and the main vents hardly nothing on high. I have checked all vac lines under hood which are fine and i have a new blower motor( and its the correct rotation). Theres a door behind the glove box that i think uses cabin air and it works and theres another one i can see next to the gas peddle that also moves. I can hear the motor running hard like alot of air is going somewhere just dont feel anything on all motor speed when selected to the vent that blow on you. Kinda stuck at this point? 1999 2wd
