2005 ****box hit 206000 miles and last night went to use heat and got nothing but cold air, installed new radiator, hoses and tstat about a year ago with a back flush, when turning temp **** there is no change in air. thinking blend door actuator is fubar. but the **** to change air direction seems to work fine when changing from floor to defrost and what not. all fuses seem good. not to sure if **** is fubar, anyone have issues like this and fixed?

 

Sounds like something is up with that door. I have a friend with a 2005 Ram that had this issue though. After a lot of tearing into things, he revealed that he changed the coolant and didn't use mopar approved. Long story short - this clogged up his heater core. Had to do a serious flush on the core.

 

I had a similar issue with my 05. I was able to remove the glove box and give a little tap with a screwdriver to the actuator. I got lucky and it started working again.

 

went out last night and kept moving switch and got blend door to move, ordered actuator. thanks for the help.

 

Good to see its working now. Hopefully the new actuator will take care of it.
On a side note, with that mileage and the other coolant related stuff you changed, have you done a water pump yet? I ask because it looks like mine is getting ready. Not really the pump, but the gasket has developed a leak.

 

replaced pump once, had the weep hole leak.
