Sun roof ECU failure

[neil30076]

My 98 Disco 1 sun roof ecu has the classic heat failure - both roofs open when the key is inserted when the ECU is very hot. Does anyone have a diagram of the internals of the ECU, I have the Rave diagram showing the motor, switches, etc.

i dont know about a diagram but you can remove the board with the ECU box still in place by removing the sunroof switch panel. hopefully you'll just find a crappy looking solder.

Good suggestion, thanks. I'll post my findings later.

There are 4 solid state relays on the board, some of them stick when they get hot. I ordered replacements from digikey online they only cost $1.69 each, installed them and good as new.
