Blower resistor card

by chance is that underneath the dashboard by the front passenger seat?

Issue 1.
When the ac is OFF, the vehicle voltage drops from 14.8 or thereabouts to about 13.4 or thereabouts.I find that really weird
Issue 2.
I was told by an ac guy that the ac fan is malfunctioning and not coming on sometimes.He said that when the fan doesn't come on , there is a safety mechanism that dumps the ac gas to the outside.Sounds kinda weird to me also.
Can anybody shed some light on this?

Computer controlled voltage regulation where the ecu increases alternator output depending on load.
&
Pressure release on the ac to prevent damage due to over pressure which occurs if the fan doesn't work or other issues.
So both situations described are possible.

correct on #1,
i you use a simple multi meter and load the engine - you will see the voltage rise according to the load and drop off when there is less load.
i unsure of #2 as it is not recommended to vent R134 refrigerant or even worse the old R12 refrigerant into the atmosphere. obvious reasons...
cars are soon going to start replacing the old R134gas for HFO-1234yf..
