Is there anywhere in Saint Louis Missouri that I can have my "air conditioner" diagnosed. The entire system was replaced but we think when we replaced the dashboard some type of vaccum line was not connected because the air door does not change with the controls. The heater is so good in the winter. I am disabled now and cannot get under the dash and bend and stoop anymore. Please help

What exactly is not working? Just a blend door?

I really do believe it is just the blend door. All of that actuator and parts were replaced. We literally rebuilt the entire system. Does the blinking codes tell anything. I am no expert but I have been around people that were at the time of the rebuild. Then entire air system was replaced.

If the digital display is showing codes, then yes, you have a fault somewhere in the HVAC controller.

Rebuilt or replaced? That controller is not something a local repair shop is going to rebuild.

I was just wondering where would look to try and decipher the codes that could lead me to the problem

The vacuum operated door will not work if that vac line is not hooked up. Need a scan tool to get codes.

Christian Brothers is a chain that seems to have a good reputation wherever I've been. Looks like there'* one at:

Thank you so very much, I will be contacting them. This Bonni is worth the effort, she runs like a top and I have maintained her all these years in first class condition. She passes inspection every two years. Thanks again.

Glad I could help. Please return later and let us know how it goes!
