No heated seats / rear defroster at or below 32 degrees

Question

Have a 06 Trailblazer, with the INTSL- + installed. I have yet to see the heated seats or rear defroster turn on when the temperature is at 32 or below. Was I missing something when I hooked it up. I didn't use datalink when hook up to the alarm.

Answer 1

I believe the module is monitoring engine coolant temperature, not ambient temperature.

If the car was driven anytime in the last few hours, or is parked in the sun, it's likely the coolant isn't cold enough.

Have you tried this with the car parked outdoors in the cold overnight, when the temperature is lower than 32?

Also, on many vehicles, the defroster turns on but the indicator doesn't.  After remote starting, put your hand on the glass to feel if it has warmed up.

My 08 does not turn on automatically either.  (i did use the data connector)  I believe only they Digital Hvac units turn on automatically.
