A/C suddenly cycling through modes?

[stk910]

I started having an issue with my A/C a few weeks ago.

While the A/C is on, it cycles by itself to a different "MODE" every minute or so. By that I mean, if I have it set to blow through the upper vents, it will switch "MODE" and start blowing through the bottom vents, then switch to both, then switch to the defroster, and keep cycling through modes by itself.

Is this a feature of the system, or a problem? Did I hold a button too long to cause this? How do it get it to stay on one mode?

Thanks

I've not heard of that before, sounds like you have a faulty unit.

I'm no electrician but I'd say faulty unit too

Alright, thanks guys. I haven't read about this problem anywhere either.... :/
Time for a new A/C control unit!
