Blower wont switch to defrost when selected..keeps blowing..vents

This answer was rated:

blower won't switch to defrost when selected. It just keeps blowing out of mid vents.

Thank you for choosing JustAnswer and allowing me to help you resolve your Toyota questions!

 

Do you have automatic climate controls or do you have manual air-conditioning controls? Do any of the other modes work or is it just stuck on the vents?

checking on other modes, 3 min

 

Let me know also if it is automatic air-conditioning.

it is automatic i believe, you select up or down on a temp setting...if you keep pressing lower temp it goes to max ac. The only mode working no matter what i select is the vents, it won't blow in defrost or feet area..it shows it on the digital display as i select the different modes but will only blow out of mid vents

 

This is automatic climate control. There is a actuator assembly on the driver side of the air box. This is located just up from the accelerator pedal and above the carpeting panel. This controls the different modes selections. I have seen several different things go on here. The first being the actual rotating cam that has several notches in it that controls the position of the door can get dislodged or stock. The other possibility is the actuator motor itself is bad. While selecting the different modes use a flashlight and monitor this rotating cam and actuator motor to see if you're getting any response from the actuator itself. If you see it starting to rotate and the cam gets stuck then you know there is an issue with the cam gear assembly. If you get no response or no movement that there is a possibility the drive actuator motor is bad or the input from the control panel is not working correctly. The weakest link is the actuator motor and cam gear assembly. Let me know what you find.

I checked the actuator assembly and sure enough it wasnt working...i then looked at it from another angle and saw a socket with no plug in it. I found the plug hanging around up higher in the dash...grabbed it and plugged it in and now voila...i got all modes working again..thanks for your help
