If you have vacuum at that line inside the engine bay, then check the HVAC switch at the dash.

Why does my Dodge Ram 1500 have no heat?
Either your heater core is blocked and isn’t flowing coolant anymore, or your blend door is also messed up.

This is the weakest link in the blend door system.

This truck has a little over 92,000 miles and never even been on any long trips.The dash cracked and had to be replaced, Dodge did pay for the parts but we had to pay for the labor.

I am having an issue with the temperature control settings. It either blows full cold or full hot no matter what position the switch is in. A/C works great, heat works great, just nothing in between.
Why does my Dodge Ram run at all times?
The AC system is designed to run at all times to regulate system pressure and lubrication. The AC should be locked on when the selector is in MAX AC setting. Any other time it should kick on and off. You will also notice that the AC will run more frequently on the defrost setting. Took me a while to get back here, but thanks for the info.
