radio bezel/blower repair



Hello folks,

Pulled and repaired my heater/AC blower today. Lots of rust in bottom 
bearing but otherwise OK. Water collects at the blower bottom through 
the cooling tube, suggest drilling small drainage holes when you have 
it out or replacing it. Better still is to increase tube penetration 
into the duct by cementing a smaller ID tube into the larger one.

Also pulled and repaired the auto tranny electronics, rebuilt the A/C 
mode control and leaked checked, added oil and charged the A/C 
system. Was a busy day. I recall reading that DMC had issued an old 
service note to reduce the R12 charge down from 2.8 pounds
to 2.2 pounds, anyone familiar with that note?

Thanks to all who suggested the foam on the rear of the heater box
to solve the low airflow problem, that indeed was the culprit.

The bezel on my Craig radio is warped so I'm looking for a new one.
(I'll buy the entire radio if the price is right.)

I'm machining tig welding up a new SS pickup assembly for the fuel 
pump. It'll replace the hose and be a straight drop down (or slight 
offset) to a custom SS baffle assembly. Anyone tried this kind of 
thing before? Have to keep the return line away from the baffle or 
may have problems when the fuel level is low (proper baffle design 
will prevent this.) This could explain why some of you are having 
suction problems even with the spring installed. 

Changing most of the coolant hoses under the car to PTFE under 
stainless flex used in aircraft, and SS coolant bellows for supply 
and return at the engine. Anyone done this, or anything else, to 
improve MTBF of the cooling system? 

Going to change the wiring also. Studying the schematic shows an 
appalling lack of design expertise. For instance, too many things on 
the accessory relay that shouldn't be. What other car allows 
energizing the A/C clutch and fans with the key in the first position 
and the engine off? (There are lots of other things hot in the car 
that shouldn't be hot in accessory.)

Also, the car doesn't seem to have a fusable link for the main power 
circuit and there is too much wiring upstream of the fuse box without 
any overcurrent protection. Don't get me wrong, I like my new toy but 
I've seldom seen an electrical system so poorly designed.
