It was -30C last night (-22F) and that is certainly too cold to be working on a vehicle outside...

Anyways, the remote start still works, but as long as the remote start is engaged the fan does not blow and the HVAC console is not working, although it is illuminated and the clock is displayed. There are also a bunch of lights illuminated on the dash: air bag, brake, abs, 4-lo and center diff lock. Once I put the key in the vehicle and step on the brake to disengage the remote start the lights turn off and everything goes back to working as expected.

Hopefully someone has a thought here cause I am scratching my head. It worked perfectly for over a year then all of a sudden breaks? No idea...
