Fiesta MK4 September 2000
The front near side sidelight is intermittent. I removed the headlight unit and checked the bulb which tested good. I replaced the headlight unit. The side light is still intermittent. Banging the headlamp unit with a fist brings the bulb back on again.
I noticed an intermittent sound coming from around the near side head light unit which seemed to follow the intermittent side light. Sounded like a motor or pump.
What motor or pump is in that area and is there a common connector which may be intermittent in the area?
Thanks
