ECT/PWR not staying on.

02 4Runner 207k.. I always leave the ECT engaged because I find I get better gas milage. Noticed earlier it wasn't on.. pressed the button and the gauge cluster light came on, but when I let off it shut off.. it lights up but won't stay on? Bad button or something else?

If the indicator comes on while the switch is pressed then the circuit is good and the switch is your problem.

That's what I figured... Guessing I'll need the whole piece (defrost, ECT, rear window control) to replace the button/switch
