I have no front heat in my 2006 Pontiac Montana van, the blower blows only cold air. I have replaced 3 actuators under the passager side. Do you have a diagram for the remaining actuators for my vehicle. Also, wondering if the problem is something else, ex: heater hoses. The block gets hot, but no heat comes into the front of the van, only cold air. Thank you.

It does sounds like you have a blend door actuator that has failed here is a guide to help you see what you are in for when doing the job.

Both heater hoses are hot so I think it is the temperature blend door actuator like you said.

One door further into the under dash was stuck, when I moved that, heat started to come in. But stopped again. Not to sure how to replace that actuator, and how many more actuators there are to check. Can you possibly supply me with an image of all the actuators, where they are and what I need to get them replaced. Like I said, I have replaced 3 that were under the passage side panel, when I replaced these, the clicking stopped, and heat! Thanks so much for all your help!
