Am contemplating checking the defrost Vac. Actuator on my wifes 88 300TE. As I understand it is located behind the liner of the glove box. What is the procedure for removal of the glove box?

Would a bad defrost actuator be the reason I have cold air blowing out of the defrost vents while the A/C is on (also blows out of the center and side vents)?

Also should there be a noticable differece when the recirc. button is engaged? I don't notice much change if any.

Thanks,

Ed
