fan switch not working, 78 280Z

[sbaker78]

Hello,

My fan switch stopped working today, which is a bummer when it's 90+ outside. The A/C was blowing fine on the way to the store all the way until I shut the car off. But after I came out of the store the blower won't blow at any speed.

I've only had this Z for about 3 weeks. There have been a couple of times when I would have to jiggle the lever to get the blower going.

I haven't seen anywhere that there is a fuse for the fan switch. I have the FSM, so I can see how to take it apart, but there is no mention of a fuse.

Is there an inline fuse for the fan switch on a 78? Or could it just be a bad switch?

Any ideas are appreciated!

Thanks,

Sean.

hmmm, I have the same year....

Try easy first, take the center panel out and inspect ,do you have a mutimeter?

The blower has an inline fuse in the 240Z, I would not be surprised if the 280Z was the same.

Check the fuse at the passenger side fuse box. Check the contact points of the fuse too. Occasionally, I have to rotate the fuse so it makes contact again. Minor corrosion. I'd bet you find the answer right there however. My 77 does not have an inline fuse other than right there.

No inline fuse in a 78. As IdahoKiddd suggested, check the fuse. Left side of the fusebox, third fuse up from the bottom, 20A. which is labled AIR CON/AIRE ACON whether or not you car has AC.

I'll check that fuse tonight. I guess I didn't think that could be it, since the blower does not blow for any air setting (AC, heat, vent, etc.). But I will go through all of the fuses tonight. If that doesn't do it, I'll pull the center panel.

Thanks!

Thanks for the reference, I see it now. I was thrown that the blower didn't work on any setting, so I didn't think it was the A/C fuse.

I just changed the fuse, all is well. Which is good because it will be warm this week! Checked all of the other fuses too.

Thanks for the help!
