Looking for Century Class Air Line diagram

TY ! One question: How to tell the difference which one I have? Water-valve controlled or the other one? VIN# L91294

 

u have blend air style

 

blend air has mode doors that control the air flow through the evaporator or heater core. depending on what setting you have it on. water valve controlled has a valve on the firewall underneith your air filter housing that controls the hot coolant flow through the heater core.

 

How can I get ( vin# M38296) air distribution and valve locations for 2004 columbia

 

Thank you for the diagrams you have provided. What would be the cost of Turbo and charged air cooler on Vin# M6298 Thanks

 

Any Ideas on why my p/w switch on the drivers side stopped working but the pass. Side works great? Tried several switches with no luck and traced the connector on the inside floor. Last 6 is B54876. Thanks

 

Duplicate post. My mistake

 

Regarding the air system & condensation in the lines, I know it can get bad. Is there a way to clean out these air tanks without infecting the rest of the entire system?
(Referring to the P&S tanks on the tractor... my drains are all plugged up & wanna replace them, but figure the new ones will likely get plugged up also.)
