The driver side works fine. This problem only involves the passenger side. Turning the car off and back on sometimes clears the issue. I determined it was the blend door actuator and ordered the part. I'm trying to install it now but don't see the part after removing the under panel. Do I need to remove the glove box?

Hi,

They can be a bit difficult to find. If you look at the first pic below, I highlighted the actuator for the right side.

To get you started, here is a link that shows in general how it's done. You can use this to help guide you.

If you look at the remaining pictures below, they include the directions for removal and replacement specific to your vehicle.

I hope this helps. Let me know if you have other questions.

Take care,

Joe

Thank you, Joe. I got the part installed and now it seems to be blowing cold air each time. Problem is that the cigarette lighter and radio don't seem to be working. Is the wiring in the glovebox somehow connected to the wiring for those devices? Also there was a cable of some type (brown) holding the glovebox in. I had to pull pretty hard to get the cable to pull out. When I went to put the glovebox in, I see now way to hook that cable back up so I just left it loose. Is that a problem? The light in the glovebox also is not working? Perhaps that bulb burned out because the glove compartment was open for a couple of days I think.

Hi,

I'm glad to hear that took care of the problem. Good job!

There is a cable that prevents the glove box from opening too far. That won't hurt anything. As far as the radio and lighter, what I need you to do is start a new thread. We are trying to keep the threads specific to one topic. I hope you understand. Simply copy and paste your question related to the electrical issues to this link. I will watch for it.

Again, I hope you understand.

Take care and I'll watch for your new post.

I swapped out the Audio fuse and the cigarette lighter #2 fuse and now everything is working okay. Seems awfully coincidental that two fuses in different boxes would blow after I did some work inside. Thanks again for your help.

Hi,

Glad to hear it's fixed. Please just make sure that the fuses used as replacements are the same amperage as the original ones.

Take care and please feel free to come back anytime in the future. You're always welcome here.
