2000 Ram 1500 heater

Hi - new visitor here - thanks for the opportunity. I took my 2000 Ram to the shop yesterday for a new water pump and belt. All of this went fine but now I have no heat. I've checked all of the vacuum lines I can find, I can feel the heater core behind the glove box and it's hot and the blower is working fine. The shop is closed and I need to have my truck at work Monday. Could it be air blend and if so is it electric or vacuum? Is there any way to "rig" this into the correct position until I can fix it? Any help will be greatly appreciated.

Mode Door = vacuum motor
Blend Air Door = electric actuator
Fresh/Recirc = vacuum motor

Nice find JIM. With this recent water pump job and this problem right away I suspect it might not be properly filled with coolant - even hot air will make the core hot to the touch but not transfer heat worth a damn. Check level at radiator cap and then adjust level at recovery tank,

Thanks guys, the coolant level is good and flowing. I'm really suspecting the air blend but I'm having a hard time believing the coincedence of timing. The last time I had the truck fixed there it was the air conditioning and I lost the cruise control. It seems a bit of a chore to get that far into the dash - any diagnostic suggestions before I drop another $1000 on the truck? Thanks again.

The coincidence is uncanny?? JIM found that the blend door is an electric actuator. Perhaps you can get a peek or hand on it going up from under passenger's side lower dash or thru the glove box. I don't know but it might be electrically controlling a lever that you could get at. Do the other functions of the control head work?

Found the actuator - thanks - unfortunately there isn't anything exposed enough to get a tool on. Yes, everything else works. I can't dismantle anything either due to proximity to the floor. It sounds like I should brace for another bill huh?

jj, I think the blend door actuator is electric per the previous posts from 2 month ago.
