Ok guys, please help this ole boy out. Got a 1997 Ram 1500, 4x4 360. Got NO HEAT.
Flushed out the heater core, it was not stopped up. When it is at running temp, both heater hoses are hot. Got NO heat. Help!!!!

 

Blend door broken?

Is there any change in temp at all when you turn the ****?

 

None, back when it was warmer, the a/c blows good cold air. The temp seems to stuck on cold.

 

On yours, the blend door is operated by a cable. Unfortunately, all of that is on top of the heater box..... so, unless your dash has disintegrated, access is a pain.

You can feel the axle for the blend door on the bottom of the heater box, just above the trans tunnel, toward the passenger side. It sticks out a little bit. Put your finger on it, and turn the temp ****, does the axle move?

Another option would be to pick up a cheap bore scope, and stick that in there and have a look around. See if anything obvious presents itself.

 

So the 1997and older dont have the actuator on the bottom of the dash as you are describing.

 

I have a 1998 as well, everything under the dash and behind the glovebox door are totally different.

 

I think the little electric actuator for the blend door came about in 2000, or 01. Maybe late 99..... My 98 is still cable operated. But, I have an early production 98....

 

so how do I get it to heat and not cold?

 

Need to find out why it's not working first. If the blend door is broken, you will have to pull the heater box. Which means the dash needs to come out.

 

what if I can get some type of tool to turn the rod on the heater core?
