check for faulty brake light switch on steering column under dash

sounds like the alternator is not charging. check charge rate. check fuses allso

First of all if the wiring burnt up there is a definate short in that cicuit, and by the sounds of it your clutch on the a/c compressor , or the compressor itself locked up, first with engine off can you hand turn the a/c compressor and clutch? if no that is your main problem that may have come about from not enough freon+ oil charge in the air conditioning system when the compressor was last replaced.
If all checks ok then perhaps you had a short in the a/c cutoff relay. not allowing the com[pressor clutch to disengage and kept the compressor over working until it heated up the harness supplying the a/c compressor and cut off relay.
First the wiring harness needed can be located at www.globalspec.com,
there you should beable to locate what you need as far as the a/c cut off relay goes try you local foreign auto parts store for this as it may have been the cause of the wiring flare up, you cant determine once something is smoked...you need to restart everything from scratch.

It should be next to or behind the blower motor, which should be behind or below your glove box.

Good luck!

WHEN HAVING STARTING PROBLEMS.FIRST OF ALL CHECK BATTERY CABLES IF THEY LOOK VERY OLD HEAVILY CORRODED. REPLACE THEM.IF BATTERY CABLES GOOD AND TIGHT.CHECK BATTERY VOLTAGE.IT SHOULD BE 12.5 VOLTS.IF NOT CHARGE CHECK BATTERY OR REPLACE BATTERY.IF BATTERY CHECKED OUT GOOD. REMOVE HAVE STARTER CHECKED OUT AT ANY AUTO PARTS STORES.THEY WILL DO IT FOR FREE.DUE TO LOCK OUT FEATURE TURN OFF RADIO FIRST BEFORE REMOVING BATTERY NEGATIVE CABLE.THIS WILL KEEP YOU FROM LOSING RADIO PLAYING CODE.

FUEL FILTER IS EITHER NEXT TO FUEL TANK OR ON DRIVER SIDE OF THE FIREWALL.

u need to replace all gaskets when replacing the water pump.....and if there was washers on it when u took it off then yes if not then no...anything else jus ask

Black smoke points to unburnt fuel. I would start by replacing the spark plugs and wires if you have not done so in the last couple of years.

if you take your car to Autozone they can check for codes at no charge.

better take it to a mechanic, I have never heard of excessive pressure in cooling system not being a head gasket. It always is.

Please stop posting useless responses like Bob above. This helps NO ONE!

Im not sure about that year make and model but usually there is a censer on the brake peddle next to the fire wall, that may have gone bad. but check the simplest thing first, if the fuse hasn't been changed in a whyle, go ahead and change it. Thair may also be fuses in the engine compartment as well.

the switch rarely go.its usualy the relay located in the panel behind the ashtray.

Hi there
you might be able to fix this problem by removing the orange colored sensor (from the relay box) to diagnose it.also make sure to see if the pins have invisible non-conductive corrosion on them
in other words sand the pins.lightly Then see if all of the brake lights work.ok just sand the pins and replace the sensor.if needed: refer to the owners manual for the location
also your local autozone or the dealership will be able to give you a online diagram for the wiring for this too ok?

Your cat converter sounds like its plugged up,look on your intake and see if it real black

the coolant lines for the transmission cooler are on the radiator and is is separated internally from the engine cooling.radiator.
there may be a rupture internally in the radiator and you are getting coolant into the transmission.
hope this helped
