after took my climate control out to experiment the lighting with led my gf was complaining about heater not working 
lol so this morning yup it was cold outside had to put them back in so kids will be warm but once i got everything hooked up cable on both ends and plugged it in it works but it blows cold air like thermostat is stuck closed it my temp is at operating temp
btw last night i flushed out water to put some coolant in the system it might have some bubbles in the system
