Sounds like a fan failure. It's likely not wiring or the ECU. If the fan ever not blows air, unplug it, remove three screws and it falls on the passenger's floor. Hook it up to 12 v (polarity doesn't matter for a short test) and see if the motor is OK. It won't work on any A/C level. Does that still mean bad blower resistor.

There are several things that may cause your blower motor to stop working. The simplest cause would be a blown fuse. If you replace the fuse and it quickly blows again, then you probably have an electrical short. Disconnected wires on the exterior of the blower motor can also cause it stop working, and if your blower motor gets dirty, it can get clogged or muddy which keeps the fan blades from spinning.

As far as the noise and lack of air goes you will need to replace the blower motor and blower wheel also.

Keep us updated.

Your best bet is to bleed the entire system starting with the wheel farthest from the master cylinder, and working to the closest one.
Also, if you have drum brakes on the rear, make sure they are properly adjusted as poor adjustment will cause a "low" pedal.
The cap you refer to with wires is the resivour fluid level sensor, and the ring keeps fluid in and contaminants out.

Need to replace blower motor on 1990 honda accord ex

It's above the pass side floorboard, kind of behind the glove box, but lower. You'll need 8mm or 5/16" socket. Loosen the bolts, lower it and unplug it, pull it out. Don't throw it away, sometimes you have to keep your fan blade when you buy a new one. A junkyard will give you one with it still on...

Blower wont turn off

If you turn the key off and it wont shut off the heater then there are some interesting things you need to check. The first would be the whole ignition switch. When you shut off the key, the power should stop to that accessory. If that is okay then you need to check the controls for the heater. The issue with no heat is one of a blend door being stuck and this could be the controls again.
