Car pops this fuse every morning for the fans and air pump, EVER SINCE I CHANGED THE OPTI AND WATERPUMP, NEVER POPPED UNTIL I HAD DID THAT...

P0412
P1641
P1642


Keeps throwin the codes like crazy, like each code twice, sometimes just 1641 and 1642, what the hell is going on with this car? its driving my crazy, i gotta change the fuse, use the scanner clear the codes..... what the hell is doing this, im gonna take off the connectors and spray some moisture displacer in em..... ALL OPINIONS. THANK YOU IN ADVANCE........

 

My guess is the AIR pump, since you seem to indicate it happens in the morining and that is when it would first come on. Probably some moisture in it.

 

what can i do to fix this? its a pain in the *** almost every day bro! i wanna scream at the damn thing!!

 

Most of the time it is corroded wiring inside the pump and replacement of the pump is your option. I am not sure if you could open one up and do anything with it. Possibly.

The other option would be to remove it and have it programmed out of the pcm so there would be no SES caused by it not being there. That option might depend on your local emissions code, though.

You could unplug the pump just to keep the fuse from blowing, but it will probably trigger the SES on your 1997.

Maybe someone else can chime in with their experiences.

 

Mine has been blowing the fuses lately too. Not as often as yours, but about 1 a month.

 

This cold weather may be loading the air pump a bit extra... seems moisture is a possibility, and it freezes, inside... mine has been cranky too[lights dimming when it starts, etc..]
Maybe unplug it til it warms up some..

 

yeah mine did it like once a month, now its like every morning, I guess I'll just keep doin what im doing for now, gonna have the egr deleted and the air pump after i do my header install.. but it wont hurt anything if it keeps popping the fuses?

 

Im having the same problem. But i removed my AIR pump. WHen i replace the fans fuse and crank the car the fuse blows about 1-2 mins after. Does it everytime. I dont know if my headers have burned some wires somewhere or what. I still havent figured it out.

 

Rob,
Sounds like my car but I got the air pump still...... Hmmm, all I know is its WEIRD but at least some of you other guys are dealing with this too, anyone have these symptoms and find a cure???

 

POPPED IT AGAIN THIS MORNING!!!!!!!!!!!
