:confused:

Hi, anyone knows about the electronic box located in front of the air filter that controls or has to do with the fan, a/c compressor and idles (because of the voltage, i think), since the mechanic put the fan in direct (when i had problems with the temp. sensor)starts my problems, now my car started with some trubles, after a few minutes the idles goes fine, but when the engine gets hot and the fan started to work the car lose a lot of power, by the 4th time that the fan start and stop to work (normally) the car feels so bad and i have to gas a lot, and if i stop it the idles goes down. Now the a/c stop to work and i got a check engine. i changed plugs and wires, cam sensor, probe with another dis module, put some dielectric grease on it, check fuel pomp, 3 temp. sensors, one oxigen sensor, i change the eec computer ones, etc, heeeelllllllllpppppp this wekend probe with another "box" and runs fine, but when i started the a/c the idles goes down and the car dies, i think that the the problem is the cable are inverted or something, please i need the diagram and that somebody expert on the functions, the mechanics are so dums here and i lose a lot of money.

thanks

You lost me could you seperate the problems.

The box located in front of the airbox is called the IRCM It controls the high and low speed fan and a few other things. Did you get the fans working? Did you pull the codes? All you need is a paperclip. Look in the FAQ under the forums section.

ok, the fan is new, two speeds works, but I had to solder the temp. sensor in the tube near to the radiator and I joined a largest two wires to make it work because in its original place (near to the DIS) don't work even if I turned on the a/c, now I have two temp. sensor but the original one only serve to stopper de friggerant jajajaj, but like a said, when the fan is on idles goes down and If I gas the car doesn't respond, do i need a v. meter to check all the wires of the IRCM????? I check the FAQ section, but i didn't see any information, what can i do?????

thank's

Unless you can see current flowing through wires, yes you need a meter. If you plan on working on your car I suggest you invest in some tools. #1 would be a Chilton, it’s not the best but it is adequate. #2 would be a meter. You can usually pick one up for about $20. What exactly did you solder? The wires for the connector or the fitting?


“I joined a largest two wires to make it work because in its original place (near to the DIS) don't work even if I turned on the a/c,”

What?

“sensor but the original one only serve to stopper de friggerant jajajaj, but like a said, when the fan is on idles goes down“

You IAC (Idle Air Control solenoid) could be bad, and I’m not sure what jajajaj is
