I have no heat on passenger side , 2000 Grand Voyager.can anyone help!!

 

Welcome to DF
Do you have heat coming from the driver side? First thing I would check is the cooling system.

 

Thanks for taking the time to help.
Yes we have driver side heat, all we have on the passenger is full cold air, AC is very cold , can't blend the air like you can on driver side.
I believe the problem may lie with the air blend door based on other threads I have read.

 

I think you maybe correct on the blend door.

 

How does one go about changing the blend door, I have looked on this site but have not found instructions on how to do it.

Thanks for your help.

 

Personally, I'm leaning toward the control head. It was very common for the temp slider to go bad so when you slid it back and forth, the resistance wouldn't change. On a 2000, you'd have to check it with a scan tool.

 

Thanks . Is there a special scaner for the H/C?

Sorry, I only know enough to be dangerous!

 

I ran the Calibration test, failed ( 2 simultaneous flashing LED's).

Would someone like Advanced Auto have a code reader I could use, or do I need to go to a dealer?


Thanks again.

 

I guess I'm not sure. Doesn't hurt to stop by and ask if there is one close to you.

 

I got a control head and tried it , same results, I am noticing that when the test is running and the driver side changes temperature, the passenger side stays cold and never changes.

I think it may be the air blend door.

Anyone know how to change it out.

I had the dash out last year to replace the condenser for the A/c, so I checked the electrical connections and they are good.

Help !
