Looking for some guidance here. My 2000 X5 has the duel climate control panel and is having issues. The unit goes on and off especially within the first 15- 20 min of starting car. if you try to increase or decrease the temp it goes off, if you change fan speed it goes off. This goes on for 15 min or so. Then it kinda stabilizes and system works. I have changed the final stage relay ( twice) and this did not help the issue. It kinda just has a mind of its own on / off then eventually it works properly. I suspecting its the actual digital display panel on the dash behind the button panel that I also replaced. Thoughts suggestions ?? Really don't wanna just throw parts at this thing. Thank you
