My first Post:) Heater Issue

[RoadHog]

Hello gang, My heater and a/c on my 1995 325is will only work on the highest setting . Has anyone had this issue and how do you resolve it?
Thanks 4 your input:)

Hey, welcome to the 'Fest!

I believe this is commonly caused by the "Final Stage Resistor" on the unit. It's not too hard to change, and isn't pricey if you do it yourself (you're looking at big bucks at a shop though).

Thanks Chad, I'll take a look at it this weekend.

do you have a analog or digital system?

The control units on digital systems are known for going bad.
