    My brake light has been on for sometime and now recently my battery light comes on and then fades but not all the way off and then flashes, I also notice the dashlights flashing occasionally too.

    The brake and battery warning lights recently came on while I was driving my '01 Rio. When I reved the engine the warning lights dimmed. I was going to try replacing the alternator and belts, but in a Rio this seems to be major surgery. Any ideas?

Now i could be totally wrong here but i would check wires on stop light switch first to make sure they are not loose,thenif appear ok remove the dash and look at connection on back of speedo ,if they appear ok then look at printed circuit.but it could be fault in ECU and this would require the relevant software to check it out.if its in america then a scanmaster will do it but if europeon then dealer most likely as europeon cars uses different software and some are encrypted

1999 3.2l. Why are battery and brake lights on?


was not on before the new alt,? is alt new or used.?
or came on only after the new ALT?????????
my guess, is 2 failures.! (one ignored and 2nd grew)
on with engine running, guess yes.
Good question and is same answer on all cars.
1: engine rpm too low, what is yours (below 80 rpm)
2: fan belt slips. bad tension pulley (weak and old???)
3: Alt bad, or its wires bad.
4: brake level low, (@MC) or hand brake switch stuck on, or other brake failures. a plenty, scan the PCM and ABS if you have ABS.
id not drive it with the brake lamp on (Savvy?)
the battery light is really the ALT charge lamp.
it glows anytime the Charge system can not charge the battery
if you drive far like that, the engine will stall and not crank.

5: the horn fuse power the alternator, so check the horn fuse
10amp , key on, 12vdc on both sides of fuse is needed/
fyi: the meter fuse runs the charge lamp, if said lamp is dead bingo.
6: fact 2, the PCM does NOT run the Alternator on the 3.2L .
7: alternator case not grounded right.
8: battery is bad, causing alternator to drop off line
9: battery cables bad, at the 4ends or they are bad.
10: the plug on the rear of alt is bad or its wires or pins rusty.


brakes:
the brake lamp has 3 inputs ("OR" logic) master cylinder level low.
the hand brake lever and the EBCM (electronic brake control module)
a technician unplugs each to see what causes the error.
if you unplug mC wire and hand brake wire
then the EBCM is UNHAPPY, scan it.

How do i replace the brake booster on a 98 Mercury villager


12 specific steps will help you :
1 With the engine off, step on the brake pedal several times to relieve the brake booster of vacuum.
2 Press the brake pedal down and start the engine. Verify that the brake pedal sinks slightly. Turn off engine.
3 Remove the vacuum hose from the brake booster.
4 Remove the brake lines from the master cylinder. Remove the master cylinder from the brake booster. Plug the fittings to prevent brake fluid seepage.
5 Disconnect the brake pedal from the push rod.

9 Connect the push rod to the brake pedal.
10 Connect the vacuum hose to the vacuum brake booster.

96 Thunderbird, soft brakes at slow speed otherwise brakes work just fine. All new pads. 2 new calipers and rotors 4 months ago, problem started last month. Could it be the master cylinder going?


Where the rubber brake flex hoses changed ?

Was all rust removed from caliper slides & all
moving parts lubed ?

Sounds like the job wasn't done quite right & then
there is still air in the system.

The wrong brake pads could be an issues also

The master should be okey, but should have been taken
apart & clean out the moisture around the piston

My cxheck brake light is on


the light that comes on just say "BRAKE", correct?

If this is the case first check the fluid level in the master cylinder. If it is low it will turn the light on. Top off with DOT3 or DOT4 brake fluid only. Continue to monitor the level. if it goes down again within 10k miles than there is likely a leak somewhere.

The other thing that will case the BRAKE light to illuminate is if the E-BRAKE lever is not in its full retracted position.

If there was a problem with the charging system a light would come on that looks like a "battery". You should be able to see this light for a couple of seconds every time you turn the key on.

1996 Ford Windstar 3.8L, Brake light is on-brakes work fine


Abs light on means the ABS sytem has a fault.
You can determine what is wrong by counting the flashes (they say) and then put the data in on the web.

IE abs, windstar, failure, 3 flashes.

The brake light on is most likely picking up on uneven brake pressure, or a failing master cylinder/
You may not feel any difference yet, give it a little time, feel for a pedal fade at a light.

Blowing fuses


THIS IS PROBABLY TOO LATE BUT HERE GOES.

THERE IS A CONNECTOR UNDER THE STEERING COLUMN FOR THE LIGHT SWITCH. THE WIRES GET HOT AND DAMAGE THE CONNECTION. THE BEST THING TO DO IS **** CONNECT THEM TOGETHER.
