My turn signals, brake lights, and 4-ways all work fine, however the blinking sound that the flasher unit makes is constant. If you touch the brakes pedal enough to ignite the brake lights , it stops. I traced the sound to the flasher unit under the dash and replaced it, however this made no difference. The shop wants almost $500 to replace the turn signal switch. Is this what it is?

Might be, but look at all the light sockets first, sometimes they melt a little and can cause a short
