dang man you got all kinds of lights and things going out thats gotta be frustrating! Im not sure on the hazard light button bulb, but it's probably a neo wedge type A (considering the size) the center diff lock button is supposed to illuminate too and that is a Neo Wedge Type A As for the cig ring i just used the light that is supposed to light up the ashtray and moved it over to the cig ring. and it worked perfect!
Now for your a/c button when you say its broken is it just the bulb? or is it just not doing anything? cause if its just the bulb the light that illuminates your temp control (the center one) is the same bulb that lights up your temp knob.
those switches are probably expensive! i would just get the bulbs you would probably save around $40+ to spend on something cool for the Runner I bought two sets of lights to replace all the main ones and the first time i paid like $30 for all the lights and the backup set i only paid around $23 and superbright LED's.
