I know this is going to be one of those questions which the answer will be so simple I will want to hide for a week, but any idea what
AHVAC stands for.

Thanks
Frank.

 

Maybe you refer to HVAC? That's the acronym for "heating, ventilation and air conditioning", used in the industry to indicate all those systems that perform air treatment.

Hope this helps.

 

Yeah...and put "automatic" in front of it...

 

That could be it. The cct diagram did say left and right hand side.

I have been soaking up as much info on the car as I can per day. Learn more about it.
One day I wont be able to get a warranty, so its time to start learing the systems.
Cheers.
