I have a short somewhere in the car, the taillight fuse blows, I have checked for shorts in the taillights and replaced the taillights, then I checked the headlights, all were good and I couldnt find the solution.

That sounds like a serious issue. You SAFEST bet is to take it to a certified mechanic, but if you're intent on trying to do it yourself, I suggest buying a Hanes or Chilton's manual for that model car. It will have the wiring systems diagrams and is only about $15 at most autoparts stores. Without it, there's little hope.

HI..
First the A/C. Vents and ducts are Completly APART of the
Electrical wires.. can be wires BUT outside of the A/C housing assemble.
For the Smoke from the a/c vents. Check the antifreeze level.
and see under the car for any advice of Coolant.
when the HEATER CORE. come damaged. loss coolant. and smel bad.

For the lights;
First check all the fuses. The FUSE fo the Park lights is
PARKLP fuse 25amp. Located undel left REAR passanger seat. Fuse block..
OK.. The HEAD light use a CIRCUIT BREAKER "HDLP" 20amp.
LOcated on the engine compartment fuse box.
Check the head light switch.
and the turn signal switch.
BUT your lights use a little Module called. LAMP CONTROL MODULE.. Located a left side of the Instrument panel.
You can try to locate and inspect.

OK.. i hope this help to try to diagnostic your vehicle.

Thank for use fixya. any further info. that you neeed just letme know.

SOURCE: no brake lights when i push the pedal

Its the signal light switch on the lever.
THe signal switch has all connections relating to the brake lights!
solution play around with the lever and see or get someone to see the brake lights work with the brake pedal down.
My car does the same thing! when i move the lever towards activaiting the high beams the brake lights work.
just gently push on the lever to see the lights go on.
you have to replace the switch and requires removing the steering wheel without setting off the airbag.

SOURCE: DASH LIGHTS AND TAILLIGHTS NOT WORKING

There seems to be a unwritten rule that the tail lights are on the same wire as the dash board lights ... if you have no dash board lights, neither do you have tail lights. There is a blown fuse somewhere, your job is to find the wire causing the trouble and it is likely at a most inconvenient place near a hinge.

Good luck with your repair.

When you say "all fuses good" Does that mean the fuse panel on the passenger side end of dash...
and both power distribution boxes under the hood? They are attached to the fenders and you will have to remove the metal straps running over the covers to open them. Check power wire going to each box for tightness and 12 volts. If all the fuse's, relay's, and circuit breakers are good, you may have an issue with the "Body Control Module". You will find it under passenger side dash, behind the glove box. Might even be an issue with the ignition switch.
