Hi. I have 2 problems with my 4 Runner. Its a 94 SR5 V6 4x4. First of all, my 4x4 won't disengage and I can't figure out why. Second, my left turn signal is stuck on. When the parking lights or headlights are on, the turn signal is solid. When those lights are off and I attempt to use the signal, it flashes, but it also flashes the parking lights. This just happened while I was driving and I can't figure out how to fix it or what caused it. I'll take any suggestion...thanks.
