Replace Final Stage Resistor?

[Sardonic]

Argh...went out to start my X5 last night and AGAIN..."click, click, click..."

Dead Battery.

I have some of the symptoms many of you have discussed on this forum, but not all. I still have control over my HVAC system when the vehicle is on and running; however, my HVAC system is NOT shutting off when my X5 is off and locked. The lower vent fan runs for a period of time and then shuts off and the runs and shuts off...you get the idea.

Has anyone else ran into my situation? Or do all bad FSR cause you to lose control over your HVAC system as well?

I am sick and tired of jump starting my X5 daily, and the hell if I'm taking to a BMW Dealership this soon...especially if I can narrow it down myself. All of the fuses look solid, and I know the HVAC system not shutting down is the cause of my battery drain.

Any help appreciated.
