Heater Power

[Whisper]

I can not get power to my heater blower. This is a 73 and I have checked all the connections on the blower switch and the fuses. I realize that Datsun in all their wisdom did some screwy things in the 240 electrical system.

Whisper I am currently working on the same problem.

Mine worked fine even the A/C worked. I had my frame rail replaced and now the A/C is broke, and no power to the blower.

I did find an in line fuse under the dash on the pasanger side of the console that is blown.

I replaced the fuse (20amp) and it sounded like the blower was going to turn on but the fuse blew.

I know the switch is grounded because I was trying to make sense of all the wires haning behind the stereo opening and found a loose black one.

I figured black should be connected to the body somewhere so I did just that.

What do you know that turned my blower on. And as I said it wasnt long before I relized I could move the vent lever to the off position and I had A/C.

But now, I need heat and I cant figure out why my blower won't work.

I hate taking my car to other people to get work done. It never comes back working the same as it did going in.

I will keep a watchful eye on your post. Maybe we will both benifit

The heater and blower were recently reinstalled and a Honda blower motor installed. the blower worked before it was iinstalled in the car and I have checked the connection at the blower for power. My question is where does the short pigtail from the dash harness to the blower control panel get it's power?

I'm very surprised no one has any advise on the subject yet.

Why might my blower be blowing fuses and not air?
