Hello! Coil of Heater Relay is supplied through Fuse "IG1 2" (10A)...Located in the Drivers Side Box...Contacts of Relay are supplied through "Heater Fuse (50A)...Located in Engine Relay Box...Blower Motor has a 2 wire connector with wire colors: Black/Yellow (Pin 2)...And White/Blue (Pin 1)...Pin 1=Ground and Pin 2=Battery when Relay pulls and contacts close...
The Blower Resistor Pack (Which fails often) controls the fan speed...BUT, there is a fuse inside the assembly...If it blows = No Fan...Located on the top of the heater/AC box and can be accessed through the Glove Compartment...Guru...Saailer
I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867
SOURCE: I have a 2005 tacoma,4 cylinder. My cab air blower
You need to check the fuses and see if the fuses for the fan is no good and also check and see if you have a bad connection of if the fan has gone bad.
SOURCE: I have a 2006 Toyota Tacoma the heat is always on
check the heater inlet valve. it is located in the heater inlet hose usually near the firewall in the engine compartment. It is vacuum operated but could be stuck in the open position.
SOURCE: air blower stop on AC , unable to locate fuses Please help
I really doubt it is the fuse, more likely the blower rmotor speed dropping resistor or the motor itself is defective, the motor is under the dash on the passenger/ right side, the blower motor resistor is near it in the air ducting, see photo below.
SOURCE: Is there a fuse for the overhead compass/temp
The 10 amp IGI #2 fuse controls several other components including the dome light, cruise control, and brake lights. If these are working but the compass is dim, intermittent, or dead then the control module has gone bad. You can get a replacement from toyota but I believe it costs $500+.
I offer a repair service with a lifetime warranty. Check it out:

thanks!
Might be the Resistor pack located close to the blower. Could be under the dash or under the hood, but always close to the blower itself. Usually has a flat connector with 4 or 5 wires, and two small screws holding in the duct. It may be a crispy critter. It happens... The blower moves air across it to keep it cool. The blower motor may be bad as well, or possibly the fan speed switch. May very well be the fuse for the blower as well. The blower connector may be loose. Let me know what you find.
