About a year ago, I noticed that the mist feature would work off and on. Then I noticed the intermittant/delay was acting funny. As of the last few months, my windshield washer fluid doesn't work, and the only way to get the delay feature to work is by turning the wipers on either low or high and then turning to delay. I'm not quite sure what to replace? I have a 93 chevy p/u that was acting weird also, so I replaced a circuit board inside the wiper motor (cheap fix 15.00) but I'm not sure if my T/A is the same. Any suggestions will be greatly appreciated!! Thanks.
