My AC/Heater does not blow any air in my 2006 Toyota Tacoma V-6 Pre-Runner. There hasnt been any whinning noise from a belt or anything... could it be the fuse or should i just take it to the dealer if its more complicated than that.

fins not accessible unless removed from housing have you checked and tested blend door and actuator

Surges can be from vacuum lines. Check them. Especially the rubber parts. If they are collapsed or soft/spongy, replace them. Next I would clean the mass air flow sensor and the inside of the throttle body.

low engine coolant means air is flushing throught the heater core
when dead cold engine, remove RAD,. cap
look in the hole, bingo low rad level
why? , ask/

You have a problem wit the air temperature control blend or the blend door actuator motor, most times both are defective. The parts are located deep in the dash and as such the dash assembly must be removed to service the parts.

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
