    Could not find a TSB on this . Have you tested the pressure switch/es as they show to draw through the 7 amp fuse .

SOURCE: I wash 1999 Toyota Corolla CE the other day and at

remove the spark plug wires and use a blow gun to dry the spark plug tubes of any water that may have gotten in, the blinking engine light means there is a missfire. and check those fuses with the headlights on and see if they have power.

SOURCE: Fuse keeps blowing out 94 Corolla

That leaves only a couple things that may be the problem.

1 the break switch could have a short in it, or going bad. it is located on the break pedal its self, get on the floor and push it in and you can hear it click, some times they go bad.

2 the other is bad ground or a positiave ground, meaning a wire is loose on the ground side, or there is a bare wire on teh positiave side touching the metal.

3 if the connections on the light sockets thereselves, it will cause the same thing.

bottol line is your dealling with a short of some kind, and some times they can be a bear to find,

Good luck and i hope this helps a bit

SOURCE: 93 corolla 1.8 No start Blown ignition fuse

I had a prolem like this one time a while back. what i did was got the wiring diagram and checked everything that was running through that 30 amp fuse. on the one i was working on it ended up being an injector wire pinched under the valve cover and it didnt short out till the car was driven til it warmed up and expanded after the valve cover gasket was changed. hope this helps!

Ok I have replaced the therm,coolant temp sensor and replaced the 40amp fuse the keeps blowing,causing coolant fans to not work,causing overheatin. It does fine,fans work and no overheating until I turn on...

If the A/C is on the same circuit as the coolant fans, then the A/C motor is going bad and drawing too much current. A local shop should be able to test the motor for a small fee, or, if you know how to use a multimeter, you can check the motor's resistance for shorts. You'll need to know the original motor specs before testing; the motor model #, maker, etc., should be somewhere online, or available from the maker.

Air blows warm out of my a,c unit

The first thing to do is see if the AC compressor on the engine is running and if it is check to see if the larger of the two lines from the compressor is cold, if it is not cold and the compressor is not running then you have lost the charge of refridgerant due to a leak, if it is cold and AC compressor is running then the door inside the dash called the "Blend door" is stuck in the heated air position and you must replace it and the actuator that moves it.

No sound output in 2000 BMW 328i 4dr Sedan but radio functions properly?

Hi Toxey.

Does your trunk amplifier got power.
basically amp need remote power input it is coming from your radio.
please check when you turn on the radio remote power must turn on.
if no it is radio problem or wire is damaged itself.
please check the outputs,speakers with multimeter or single 1.5v cell.
if power is ok.and the remote on signal is ok your device still not working , it is the problem with power amplifier unit.

please check and let us know the status.

What powers the cooling fan motors my ac is not cooling properly the motors come on, but they are not turning fast enough. got straight power to motors, they both work ok.

you may find that the cooling fans only run at half speed when the a/c is on they might be set that way & run at full speed when the engine starts to overheat (in stop & go traffic) the a/c may need regassing that's why it is not cooling properly.....hope this helps...... cheers..

Where is ac fuse on 2007 jetta wolfsburg edition

Hopefully it is a fuse - when the a/c goes out it's usually not a fuse... It could be the compressor, or the fan module or the pressure switch.

Here are some fuses to check:
For compressor/module
#4 on panel C
fuse #16 on panel C
fuse #40 on panel C
fuse #46 on panel C
fuse #6 on panel A

For fans:
200 amp Fuse #1 on fuse panel A
50 amp fuse #3 on fuse panel A
10 amp fuse #24 on fuse panel B

Fuse Panel A and B are located engine compartment drivers side near battery. B is the top surface with low amperage fuses, A is the front surface with high amperage metal strip fuses.

Fuse panel C is on the driver's side of the dashboard - you have to open driver's door to get to it.

The smaller of the two cooling fans should be the one that actuates only when the a/c is turned on. The larger one should actuate when the engine is running.

Ac not blowing cold air

either you are out of refrigerant (means there is a leak) or the fuse is blown for the compressor clutch circuit. check your fuse box for any blown fuses first, then if your a/c is R134a get a gauge kit and check the pressure if you can get it to turn on. it should be 25-35psi. if your car is the older R12 system you will have to have it retro-fitted.

When idling saturn ls 4dr sedan wants to overheat

Sounds like either you are low on coolant or the cooling fan isn't working. With engine cool remove radiator cap and check coolant level, top off if necessary. If full start engine and turn on A/C full blast, full cold the cooling fan should come on almost instantly, unless there are two individual cooling fans in which case only one may turn on. If no fans turn on check all fuses whether related to fan or not. If all fuses fine try swapping relays around, they are usually all the same size/style. If fan still doen't work you have either an open positve or ground side of the circuit, Which will require wiring schematics and a multimeter. If coolant full and fan/s turn on and engine still overheats you'll need a new thermostat installed.
