Yes. I think it did.

So that didn't have anything to do with the blower did it? Is the blower working?

Makes me wonder if it is something in his fuse panel and he nudged it enough to get it going again.

What do you need heat for anyway, Manfred?

But he could hear his relay. Strange.

Hmmm. A case of gremlins if I've ever heard of one.

Nope. The blower is still not working. I don't get it? I swear once I hooked up that red wire to the 7 fuse the blower kicked on. Maybe I moved a wire in the back of the fuse box or something. I haven't had a chance to trouble shoot it.

I'm planning on diving into the heater/blower motor after I under coat Betty. Stay tuned.

Could the sound have been the water pump? Stab in the dark.
So it all started when I wanted to get better gas mileage....

Hi Manfred,

I just read through this thread. Everything that dtrumbo told you on the first page is accurate for our '78s. Unless some PO did some serious bastardization to your wiring, the fuse box in the front of the bus has nothing to do with the operation of the heater booster fan.

I assume you checked the in-line fuse? It's a 16A fuse, located within a few inches of the fan relay. If this fuse is blown, and continues to blow, then your fan is dying, and needs to be replaced.

Next thing I would check is the ground. The ground wire comes off the back of the fan, and connects to the mounting bracket. Clean the connector.

If a helper turns the key to "on", can you hear the relay on the fan click?

Isn't there a spade on the controls framework that will ground the circuit when the heat lever is brought to the bottom position? Might be worth checking to make sure you didn't noodge something when you were working.

No. I went to the back and checked the blower motor running. Then I turned it on several times with the lever in the front, but thanks for the guess.

I'm sure it was a bad ground or something to do with the wiring in the front. The PO did some screwy things. I probably inadvertently fixed the problem and then moved a wire which made the blower turn off.

Question: What type/size fuse is in the in-line fuse holder that connects to the blower in the engine compartment? I just dropped mine into the dark abyss and I didnt get a good look at it. Thanks.

That should be a 16-amp fuse which is typically red. Looks like so.
