I have a 73 Vw Thing, and when I purchased it all the heater parts have been removed. I tried contacting the previous owner to see why all the heater stuff had been removed. How hard and expensive will it be to locate and reinstall everything? I know it's a very general question but it a possible thing to do without getting screwed?
Your thoughts?

Yes its entirely possible to do.

Weather you do it piece by piece or most all at once it for sure can be done. Last year - and this is not a common thing but two complete units poped up in the box NOS condition.

I got one of them here -

These will fetch in the $500 to even $1000 foe the ambitious. Those listed pics will also aid you in seeing the complete unit and parts - less the cabin ducts.

It may take some diligence but all the stuff is out there. Look for parted Thighs with gas heaters, Ask the seller to pull everything for it.

There are also plenty of "fixit" info here and you tube so you can restore one or three.

I myself have lots of vids and an ongoing thread over in the Bay forum.

I was excited that I got my heater to work again over the weekend! It had quite heating some time last fall and I didn't bother to figure out just why. (It didn't seem to be firing at that time, the fan was running but no fire and eventually it timed out.)

I got it working by cleaning up all the electrical contacts. I had been working on the contacts in the fuse area and got inspired to give that a shot.

So it worked great for a few days.

Then yesterday while driving it made a squeaking noise a couple times. They were very brief the first two times, and I actually thought it was the speedometer getting cranky.

But the third time it made the noise, I was at a stop light and quickly realized that was the heater. Before I could turn it off, though, it quit altogether. No fan run on or anything.

I haven't had a chance to check the safety fuse or the "breaker" or any of that on the heater yet.

Just wondering though, what the noise may have been and where to start.

While I was at the light, I did briefly reach in and see if the air fan moved and it does still spin.

There are only two moving parts - the fan and the pump. Most likely the fan pooped out. The combustion side lives in a harsh environment.
