[OZAPRS] HF APRS upsets the car's climate control

[Tim Ahpee]

G'day Folks,

I've just got HF APRS running in preparation for my trip at the end of the
year and have come across an interesting one. Each time the rig transmits the
fan in the climate control goes to full power. Nothing else seems to be
affected just the fan. It was a bit of a shock the first time it happened. I
was driving along and heard the TX relays go click then I was blasted in the
face with air. 

Details:
Rig: Icom IC-7000
Car: Toyota Prado 2008 Diesel
Antenna: Diamond HF30FX mounted on the bull bar

Any thoughts? I'm wondering if the RF is getting straight into the motor
controller for the fan because if the fan is off nothing happens.

Cheers,
Tim
