The engine compartment purge fan rarely comes on. Mine has only come on twice -- and I live in 90 plus degree California! Here are the conditions the fan comes on at.

From the service manual...

"Switch-on conditions for engine compartment fan (this fan pulls air into the engine compartment) The engine compartment fan is switched on when the engine compartment temperature is > 176 degrees F or the coolant temperature is > 216 degrees F.

After-running of engine compartment fan

If the ignition is switched off and the engine compartment temperature is more than 140 degrees F, the DME control module remains in readiness for another 20 minutes. During this time, the engine compartment temperature is retrieved every 10 seconds. If the engine compartment temperature is > 185 degrees F , the engine compartment fan is switched on for 20 seconds. If the engine compartment temperature is still > 185 degrees F after this time, the fan remains on for a further 30 seconds."

thanks Loren!

Need some help. I got a 1999 carrera cabriolet with 15,000 miles on it. Bought it used about 8 months ago. The engine compartment fan has never come on... Even when driving it it hot weather. My temperature guage reads a little over 180, but still the engine cooling fan does not come on.. Any advise on how to check the fan or engine sensor?

Thanks guys. You're great! I found the cable, opened the hood, and love my car again! Ordered a battery maintainer also!

:rolleyes:

Good question Viper, is it a pull handle or button Scouser? My 99 has a pull handle, when I had the same problem I had to open and lock the car with the key on the door a couple of times, and it was back to normal. The 03 with the button is a different story. But the battery was "filled" again.

The cable I used is the shiny cable, flashlight and a wire hanger, between the passenger headligh and bumper cover. Should be in there somewhere.

The side markers hole, if you can see it, should be towards the front. Look like an aircraft wire with a loop on the end. The wire hanges made it easier for me to hook it and pull.

Thanks for bring up this topic, but I still can't find the cable to open my hood. I have a 1999 996 C2 Cabriolet. I pulled down the passenger side wheel cover and still can't find that cable. I even flipped open the side marker. Where exactly should I be looking? high side/low side? Toward the front? Is it a covered cable or is it a bare wire?

Help.....
