Dead temp display

[climber boy]

Recently I removed the climate control unit from my 97 528i because one of the buttons wasn't working properly. I took off the front section, replaced the missing spring, snapped back in the circuit board, and put the front back on. Now the whole unit is back in the dash where it belongs, but the LCD display that shows left and right temps plus blower speed is dead. All the buttons light up when I turn on the headlights, except for the + and - buttons for blower speed. What's going on? I haven't found a blown fuse. Is there a reset button? I'm hoping a wire didn't come lose. When I said I removed the unit, I just pulled it forward. I did not unhook any of the wiring connectors. For now I have no climate control; no AC and no heater. Help.

While you wait for replies, maybe a look at realoem.com can get you a diagram of that system to help you out.

The loom is very tight at the rear, I changed my elec window switch last week, the main door one which controls x4 windows mirrors etc, brand new from BM, plugged 3 connectors in, 2 windows worked and 1 mirror, took it out again and one connector was'nt fully home as it only had an inch that came through the door panel, so I used a pair of long nosed pliers to get it home, so I would say one of the connectors is slightly out at the rear.
