I have 1998 T4R Limited, and my intermittent wiper function is...well... intermittent. Sometimes it works properly, and sometimes it is always on the low setting. I thought it was a wiper switch problem and ordered a replacement. I installed it today, and the same condition exists. I downloaded the FSM. If I'm reading the wiring diagram correctly, the intermittent voltage control signal originates from a relay in the switch itself. Any ideas as to why a replacement switch would not fix the problem??? Could I possibly have a bad switch contact in the wiper motor???...Thank you.
