Stanley blower fan wire question. Help please and thank you

You have to cut the blue wire, WAIT NO, the red wire. No the blue wire, yes cut the blue wire. Phew that was close. (How the hell is anyone going to know the answer this question? you took the think apart so you can see what the wires are for)

Firstly check the fuses for the fan. If those don;t work, maybe there is some debris in the blower fan that is stopping it spin?

The fan uses security fasteners to prevent dis-assembly. To clean the fan, disconnect power from fan and use compressed air to remove dust.

I own a Marvin model 1220 box fan since 10 years ago. The stand broke on the hooks part. I need the buy the same, please help me on this. It is out of stock in the Internet. This fan is fantastic, but need to keep it clean so the blades don't slow down do to dust

Blower motor is on passenger side under dash. Disconnect neg side of battery then then blower motor wires and hose. Should be 5 screws holding in motor - remove. May need to take out glove box and kick panel to give you more room. Disconnect ECM wiring and bolt from right side of instrument panel. Gently pull down instrument panel and remove blower motor and fan. Install new motor and fan. Hope this helps - let me know. Thanks.

I think your headed in the right direction. At the front blower motor, the black wire is voltage and the dark green wire ground. As you can see the thermal fuse and resisters are on the ground circuit for blower motor , the speed controls are also on the ground circuit. Any motor that uses brushes, sometimes you can tap on the blower housing and it starts running, or driving down the road and you hit a bump and it takes off. Your jumper wires should have worked, in my opinion. If you wired it up backwards, I don't know if blower motor would run backwards, I never tried it. In the past, with faulty blower motors, I took it apart and looked at the brushes, wore down to the nub.

sounds like a shorrt to 12v to me. The wire is hot and the fan is shutting off because the blower is bad, getting to hot, it will bind, causing over amperage.

If it was wired wrong it wouldn't run. I would suspect uneven tightening of the motor screws.

You say blows fuse,
Are you talking about the Blower Fan, or the Thermistat for the Compressor.
If it is the Blower Fan It may be seized as the Blower Fan motor doesn't have bearings it has a bronze bush & may be stuck. I had this fault on my 76 244DL.
I had to dismantle the whole dash pull the Blower Fan apart re grease the bush & give it a clean & re assemble. It took me allll day to pull the dash apart fix the Blower Fan motor & reasemble It works perfect now like new.

If it is the Thermistat disconnct the wire to the compressor & try a jumper wire to the compressor to see if the compressor operates. if ok it could be a damaged wire through the firewall shorting somewhere. You will have to buzz out the wires from thermistat down to the compressor & the throttle up solonoid.
