Billbo, Do you figure the intermittent heater/ac out? We have the same problem with the same car.

Haven't figured it out yet. I hope some one has seen this and figured it out. Please help people.

this can be fixed by replacing a resistor on the circuit board in the a/c control panel box or by getting one that has been rebuilt by someone in this way, this is a problem on my 1998 M3 also. it is a simple panel to get in or out by first pushing out the trip computer from below/behind, then pushing this panel out from below/behind and unhooking the two wire bundle connectors. trade it in at a used BMW parts place or open it yourself and try to re solder a new resistor from radio shack in the circuit board per internet available instructions.

You say pushing out the trip computer from below and behind and pushing out thea/c control panel from below and behind.

My question is below and behind what on each of these and how do I identify these computer panels. Sorry about my ignorance but please help.

Thanks, BILL
