I have similar symptoms as you - roof intermittently doesn't work at all, sometimes seems to be related to temperature.

In my case, it's definitely the part with the two microswitches under the latch. If I take the switch out and fiddle with the switch that senses when the roof is un-latched, I can get it to go - I've just been two lazy/cheap to replace it. One trick I've found is that if I stick my fingernail in the hole where the latch goes and pull down on the plastic flap in there, I can usually get it start working.
