2015 Toyota Tacoma Air

[coxjonjill1975_191453]

My 2015 Toyota Tacoma ac was only blowing on high setting. I replaced the Blower motor resistor and now it blows on high on all settings. Any suggestions?

Sounds like the AC module or the fan switch needs fixing.

The blower motor relay might be stuck on high speed.

The relay allows full voltage from the battery to the blower motor for high speed.

For the lower speeds, the relay opens and battery voltage passes thru the resistors.
