burners are haywire

I have a doozy of a question. I have whirlpool ceramic cooktop ser# XT1210668. Mod GJC3634RB01.

4 different heating elements plus a warming element 5 in all

Top Left Element 8" single heating element. Problem: Control knob turned anywhere from 0-90 percent heat, element heats to a certain temp (5 to 8 seconds), slight click heard and heat shuts off, then attempts to come back up to heat and then off immediately, again, faint, but audible click at control switch, BUT, at 100% High heat, element heats at High and holds heat.

Bottom left element 8" single W Bridge Control.
Single function no heat at all
Bridge function: 0-80 percent heat same as description above. 90% heat, holds constant heat. 100% high, element goes cold.

Top Right element:
Single element for small pots 0-90 percent (on-off heat as described above) 100 percent heat, holds constant heat.
Dual element for large pots: 0-90 percent (on-off) 100% heat holds constant heat

Bottom Right element: 6"in burner works perfectly

Warming Element (5th element)
Total cold in both warming mode and in regular burner mode

Is this a short or is this bad switches?
Plus I can not tell from the diagram and parts list which switches I need??
The parts list shows 4 different infinite or infinity switches (some for 6", some for 8" burners but does not differentiate which switch needed for the dual or bridge controls. Can you help me?
