    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: 2003 Toyota Corolla 30 amp keep blowing

it sounds like when the cat was changed they have trapped a wire or just moved one over a bit and its rubbing think about what items this 30amp fuse is protecting are any of the items close to the exhaust or around that area, i dont see the aftermarket starter doing this after 2 years hope this is helpful regards JR

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.

Compressor and fans do not turn on until rev engine


I passed this question the first time I read it, so I will take a stab at it now.
The fans don't come on until the compressor has pumped the freon pressure up to say 150 or 200 psi. And the compressor clutch has to have voltage to engage the clutch.
I wonder if the clutch is going and needs 14 volts instead of 12 to engage ? Or the relay that powers the clutch ?
Speeding up the engine would increase voltage from the alternator.
This is assuming the serpentine belt is tight and everything else is working correctly.
I think I would swap the relay with another and put a meter on that circuit to the ac clutch to see what it takes to engage it.

2008 Honda Civic dx rebuilt AC compressor always on regardless of controls


OOPS ! Now, it sounds like the A/C relay is constantly on. In the power distribution box by the battery, try swapping another relay for the A/C relay (which turns the compressor on), and see if it now stops. If so, buy a new relay. Good luck.

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..

there is a pressure switch on the ac drier that is the big silver can looking thing by the dash under the hood... if this goes bad the ac compressor will not kick on and the fans will not run when the ac is turned on... if the fans are not running at the same time of the ac compressor it will not blow cool..

yes, but your ac system contains switches, one low preasure switch to shut compressor down when freon is low, this is to avoid compressor damage,if low on freon the compressor will not turn on. the first thing to do is make sure the feron is full, you will need a teck to do this, i dont think you should atempt this, its high preasure you may cant hurt or damage your system if not done right.

A/c wiring


The Red/White comes from the AC amplifier into the AC magnet clutch, from termianl 13.

The White/Blue wire goes back from the AC magnet clutch to the AC amplifier, terminal 14

The Black/White wire goes to two places, via a splice splice, 1 is to the relay box, Fan Relay # 3, and 2 is to the AC Magnet Clutch Relay.
