Low voltage at cigarette lighter when AC is on

I have a 89 900t 240k miles and I have an electrical problem. There is excessive voltage drop on the Relay Fuse Panel even though the battery voltage is proper. When testing I found that I had 12 volts at the fuse panel and 13.2 volts with AC running at full blast. Point 54 feeds the relay box,fuse panel thru the ignition switch. Could the ignition switch be bad. Does it carry all that current. From Bently it appears that all power to relay fuse panel comes from the ignition switch contact #54.
Do I need to change the ignition switch?
Thanks Gerald
