Checked all fuses couldnt find one labled heater, all looked good though. yet fan doesnt work where is it located and how do you test it?
According to my wiring diagram, the blue and white wire from the blower motor gets power from the key switch. The fan switch and resistor grounds the motor.
No blower fuse is listed.
SOURCE: 1985 honda prelude heater blower fan/fuse? problem
yes there is a fuse
what kind of nest? did something chew through a wire?
could be under dash or the fuse box under the hood if you still have it check the owners manual in the glove box dont jump steps and just replace the fan could be fruitless
SOURCE: My heater ac blower isn't working on my daughters
Issue With The Motor's Relay Check for bad connection.. Corrosion.. inside the connector..
SOURCE: My ac/heater stopped working yesterday
Yes, I would check the 40A fuse for 'Heater Motor' but there may be another fuse under the dash that controls the ac/heater.
I would get a fuse tester from Walmart or a parts store included with a set of various fuses.
The fuse tester can be used to quickly test all of the fuses in a particular box in maybe 5 minutes of your time.
It's like a miniature test light that goes on when an energized fuse has a break in it. This saves a lot of time and the risk of putting the fuse back where it does not belong.

Inspect/Test/Replace
There are three basic types of fuses in automotive use: blade, ceramic, and cartridge.
Blade fuse, ceramic fuse, and cartridge fuse.
Occasional fuse failure can be due to a defective fuse. Corrosion on the end of the fuse can cause failure too.
The cartridge fuse is found on most older domestic cars and a few imports. To check this type of fuse, look for a break in the internal metal strip. Discoloration of the glass cover or glue bubbling around the metal end caps is an indication of overheating.
Late-model domestic vehicles and many imports use blade or spade fuses. To check the fuse, pull it from the fuse panel and look at the fuse element through the transparent plastic housing. Look for internal breaks and discoloration.
The ceramic fuse is used on many European imports. The core is a ceramic insulator with a conductive metal strip along one side. To check this type of fuse, look for a break in the contact strip on the outside of the fuse.
A visual check of the fuses in questions can sometimes show a burned fuse. Sometimes, a fuse can blow where it cannot be seen.
Test a questionable fuse with an ohmmeter.
All types of fuses can be checked with an ohmmeter or test light. if the fuse is good, there will be continuity through it.
When inspecting fuses, also inspect the fuse link:
