Hey everyone! I have a 75 C10 350/350. I recently got the ac system working again, running 134. The air is cold, however I am having an issue with the air coming out of the vents. When the ac is on air is being blown out of the dash and floor vents, I only want it coming out of the dash vents. I am wondering If anyone has/had this issue and if there is a fix? Thanks!
PS. The climate controls has options to select different modes, but there is only one option for ac.
