2003 Megane 2 1.4 Diesel.
Had a flat battery a couple of weeks back, left the lights on (but they should switch off when locked?). Slave started the car but since then have a number of odd faults;
Window washers/touch wipe don't work (but wipers do off the same switch, just the 'pull' functions defective)
Heated rear window and Airconditioning won't work (lights do not illuminate in switch),
Cigarette lighter not working,
The Time and Temp display won't come on unless the Radio is on.
There are probably a few other oddities. Checked all fuses, disconnected and reconnected battery (this was necessary to check the fuses anyway!) and all connectors.
In an older vehicle I'd suspect an earth connection but there are hundreds to chose from in the Megane and most are inaccessible. I'm suspecting the Interior Control Module but before I shell out, is there any master reset function or maybe something I've missed? Any help appreciated.
