RPO Code C36

I have an '01 Suburban and the code says "Heater, Auxiliary", what exactly does this mean? Is it an engine heater or an extra heater for the back. We've only had it for a week, so not too familiar with some of the options. Thanks for any info.

Re: RPO Code C36

my guress would be for rear heat, but its just a guess. i know on some of the newer GM SUVs and what not they have a seconday "water" pump under the hood. it is an electric pump that forces the fluid to the rear of the vehicle so it can heat the passengers back there.
i dont know if the suburbans have one or not, but i suspect they likely do
