I have had a 96 Wrx V Limited about 4 months now and to begin with all was good. Then one day on the way to a car show how it broke down but we found one of the inter cooler hozes had come off so an easy fix. Since then I have been going going through putting right a few other issues with car.

It has now developed a problem which has stumped me for a while. The car starts fine ever time but the idle is sometimes ok and sometimes all over the place. When you drive it randomly looses power and that generally coincides with a click from under the dash. I did think it could have been the fuel pump relay but a new one didn't solve it.

Last night a found but chance that when you turn the blower on and off you get the same noise and also the car drives different depending on if it's off, on or on with the aircon. I'm guessing its a short some ware causing the problem but electrics are not my thing. Can anyone offer any advice please
