I need your help. I have the pickup listed above, with A/C and heater. The cable that opens the vent that lets in cold air or heat is stuck in the cold air position. I pulled out the control assembly. As I pulled out the control assembly, I forgot about the vacuum harness assembly, it pulled off. I need to know in what position the vacuum harness plugs back on. I am enclosing four (4) photos of the control assembly. Please help with any information you might have, thank you, Bill H. Comfort, Texas. Pictures would be very helpful also.

Hi,

I'm not having too much luck due to the model year. I attached anything I could find, but I suspect it isn't what you need.

Take a look and let me know if they help.

Hi,

I'm glad to know they are helpful. Information is really limited because of the model year.

If you have a chance, when you get to it, let me know how things turn out for you.

Take care,

Joe

Hi,

No problem whatsoever. Keep warm! I'm near Pittsburgh. We had single-digit wind chills today. I miss summer. LOL

Take care,
