You too can have variable speed intermittant windsheild wipers. The IPD intermittant wiper relay p/n 5531, for the 850 series will work on your car. For the second generation 960's and V/S90's it mounts behind the stereo. If you put the car in neutral, turn off power at the key, remove the stereo,( use a coin to push in the brackets, then pull them completely out, remove radio) relay is on the right side, it will be about double the size of the new relay and usually will be red. It should have 203, or L 203 printed on the top of the relay. Remove old relay and replace with new, making sure it is completely pushed into the block. Reinstall radio, and give it a test.
