I have the truck listed above that the heater and A/C hose is cut under the hood on the passenger side. I am wanting to hook it back up but can't find the right video or pictures to help me out. I need help figuring out where it needs to connect at.

Hi,

Are you referring to a vacuum hose? Can you upload a pic of what you are dealing with?

If this is the issue, the vacuum comes right off the intake manifold and into the vehicle via a vacuum hose. If it is something related to the actuators, I attached a pic below showing the vacuum schematics.

Let me know exactly what is happening.

Take care,
Joe

When I try to turn on my heater or A/C it doesn't blow out at all, but my defrost works. I'll send a picture as soon as I get home today.

Hi,

It sounds like a vacuum leak. The default is defrost. Do me a favor, send me the pic so I can see where and what is broken. Chances are it has the hard plastic vacuum hoses which break after time.

Take care and I'll watch for your reply.
