1998 XC70 Blowing AC - Emission fuse
Check engine light went on. AC stopped working.
Checked Fuses, Fuse # 5 under the hood keeps blowing.
It's a 10 Amp fuse labeled: AC - Relay Emiss. Syst.
I've unplugged and checked the Air pump with 12Volts, it works
fine.
I also unplugged the only wire that was accessible to the AC compressor
clutch.
Any other suggestions how I can diagnose why this fuse is blowing?
Maybe just a Relay but I don't know how to determine which one.
Thanks in advance,
Rich S.

20days and $1100 later I've got my volvo back. Fuel pump was repalced, $700 in labor.
The fuse was blowing because of a short on the airbox heater, sensor, resistor? I don't
know exactly what it was.
The check engine light is STILL on.. the only code left is the evaporative pressure
sensor.

The receipt shows PTC resistor on the intake air tube.
$107.68 "FRESH AIR TUBE" P# V9186200
I think it was that hose they replaced. The hose itself was fine it was the sensor,
or resistor that was shorted and blowing the fuse which caused lots of other problems.
I wouldn't mind the price too much if the dam Check engine light was actually out now...
but it isn't. A Evaporative pressure code now.
And if that wasn't enough I just realized that there is a problem with the AWD...
realized it when I got stuck in today's snowstorm.
I'll be selling this car soon, can't afford to fix the AWD and that's why I got it. Too
bad, I really like the car.
