Hot/warm air only

[tigers77]

I am only getting hot or warm air from my vents even when I set the temperature to the coldest setting. I have a 1991 525i. Any help would be appreciated.

Which vents? They all do different things...

could be the good ole hot/cold air setting for the main front vents. (if you have them anyway.. if so, it is the dial that has red dots that can turn into blue dots) that is if you are getting warm air, only from the two front vents and not the side ones.

other wise, it could be the ac running on low coolant?

This is a typical fail item. It's easy to check to see if its working too
