Re: [DML] a/c blower performace observations (long)

["Walter" <Whalt@xxxx>]

My purpose for this posting was to make people aware that a previous owner
may have installed the wrong blower in their D. The performance of the
wrong squirrel cage blowing in the wrong direction will provide a reasonable
amount of air flow from the vents. But this is just wrong! I've read too
many posts about people reversing the polarity on their new blower motors to
get the 'proper' air flow. THIS IS WRONG! If you didn't keep your old
squirrel cage when you made the change, then you are screwed!

Since I usually keep several junk cars in my yard, I couldn't see ordering a
new fan from a D vendor when I had a few candidates sitting in my yard. I
put one in with a larger motor. I got nothing. I reversed the polarity and
got a good amount of air flow, but it wasn't the same as my squeaky OEM even
though the other motor was larger. I took it out and took a good look at
everything and figured out what had happened. Now my D has the OEM one back
in place with the squeaky motor. I don't want to buy a new motor only to
have it go bad for the same reason as the first motor.

The reason my original blower went bad is because it filled with water. Why
did it fill with water? My condensate drain does not appear to be clogged.
So what's the deal? It only had 9000 miles on it when it started giving
problems. Why do the bearings get wet and rust to pieces?

I do not want to replace my blower motor with the 'correct' OEM part. That
motor is too small since I know there are larger motors out there that will
fit and deliver more air. In my Olds long ago, the blower went bad. I went
to a junk yard to get a new motor. My friend noticed this larger brand-new
looking blower in an old Cadillac. I said, "No way, that is too big." But
he talked me into buying it anyway. It fit (barely). I had to remove some
insulation from under the hood so it would clear the longer motor. Then my
air blew like a hurricane! It was great! I tried putting this same motor
in my Delorean, but it had the polarity problem... and you know the rest of
the story. However, the combination of the larger Cadillac motor with the
polarity reversed with the original Delorean squirrel cage gave a better air
flow than the OEM setup. Now that I've seen better, I will not settle for
OEM. I put the Cadillac blower back in my Olds since that is still a
running car and I need the a/c working in it. Besides, I know that the D
would only fill it with water again and rust it to pieces. All the junk
cars in my stock pile used the smaller style motor like the original on the
Delorean, and they had the polarity problem. Those just won't do.

So do any of the D vendors sell the larger than OEM motor that spins in the
correct fashion for the D? I read in the back issues that there is a blower
with a larger than OEM motor that NAPA sells that is meant for a van. If
this fits the D without reversing the polarity, then this is what I want.
If any Delorean vendor sells this part, then let me know. Otherwise I will
buy it from NAPA.

Sorry to sound like an ass. I get this way when I stay up drinking. I need
the right size beer can to make a baffle for my fuel sending unit. I think
the 1 quart size in Foster's Lager will do nicely. I'll let y'all know how
it turns out.
