93 toyota turn signal and ac/heat ???

[yotared]

Picked up a 93 Toyota pickup the other day 22re 4x4 5 speed . My question is the right turn signal does not work the guy said it was something under the dash said it was a Toyota only part what do I need to fix the truck. Sometimes the right turn signal buzzes when you turn it on. Also the heater blows really weak when the heat is on but the ac blows ok but could be better. And the ac revs up and down some when the truck is idling what could be the problem with the heat and ac.

"Combination switch " is the whole turn signal, head light, high beam switch cluster, they have problems with dirt and arcing over time. my '90 Runner had similar issues. you have to pull the column covers and possibly the steering wheel , I don't remember.

as for the heat AC weak air flow issue, blower motor resistor, next to the fan under the dash 5min fix, one screw and a plug, cost $20 if that, can potentially take out the blower motor as well.

I got the air fixed it was the switch. Thanks for the info do you know if it’s a Toyota part only or can I pick it up at auto zone or a parts house?
