1990 caddy fleetwood/front wheel drive by cournoyer1

Lost brake fluid from a leaking rear wheel cylinder. Repaired cylinder and filled brake fluid reservoir with one quart of fluid.I could not bleed the rear brakes. I did not try to bleed the front brakes. The car has no brakes at all. The brake lite and the abs brake lite are lit on the dash.A gm mechanic said the abs brake system must be replaced at a cost of $3600!!!! I understand that there is a Bosch pump in the unit and it sounds like it is running all the time and not developing any pressure. Could it be air in the system that is causing the problem?
The brakes worked fine before the brake cylinder leaked. Need help!!! The car isn't worth a $3600 repair job. mcournoyersc.rr.com

Get a second opinion! Go to an aftermarket independent garage! Dealer mechanics are there to make money for themselves and the dealer! Get out of there fast! It doesn't cost $3600 to fix ANY brake problem! Trust me!

I have a 1984 Cadillac Fleetwood Brougham with a 4.1. I bought 2 wiper motors and a switch with delay and they still do not work. If any one can help me out or knows where i can get an original wiper motor i would appreciate it.

Been there done that! You have to go to a junk yard and try to get one from a car just like yours! New rebuilts don't match up! I went through heck trying to finally get one that worked!

Coolant light comes on when AC on by caddynuts

I have a 1985 Caddy Fleetwood Brougham. It has a HT 4100 aluminum engine. When driving in town the ac works, but on long road trips, the coolant light eventually turns on. AC has to be turned off to avoid overheating, then extremely hot air starts to come out of all vents including the defrost vents. I replaced the water pump, thermostat, belts & hoses, & air conditioner compressor last year. The problems started after this. I recently replaced the heater control valve, but problem persisted. All suggestions would be greatly appreciated.

high speed overheat indicates a circulation problem, so I would say your prime suspect is the radiator. These can be flow-tested by a radiator shop.
 
If that checks out, have the cooling system pressure tested for a head gasket leak, would be my advice.

My bf drives a clean 89 fleetwood but it's over heating. Water and coolant dry out fast.

Overheating can be caused by a whole lotta things. No guessing allowed. It has to be diagnosed step by step, from the obvious (is the cooling fan working? Is there a big leak somewhere?) to the somewhat less obvious (thermostat stuck? Air block in system? Clogged radiator?) to the less-less obvious (worn impellers in water pump? dragging brakes? underinflated tires?) to the most mysterious and dreadful (bad head gasket, cracked cylinder head).
 
Tests include pressurizing the cooling system to test for leaks and bad head gaskets, testing the coolant for combustion gases, having the radiator flow tested, testing the thermostat by removing it, and of course observing the operation of the cooling fan.

From what I was told from the Cadillac dealer, he said that he did a "pressure" test. He said that was the way they could find out were the leak is coming from. What do you think?

I think they didn't continue the diagnostic. You don't just do one test and then stop and shrug your shoulders...GEEZ...some of these dealers....
