On a 96, start with the basics: If it runs at all, we know that the run relay works, and fuse # 16 (30A) in the interior panel is good. If it only runs in high, the wiper hi/low relay is stuck, or the white wire between the high/low relay and the wiper motor is open, or the GY/LB wire that triggers the hi/low relay via the GEM grounding it (position #2 on the relay) has shorted itself to ground. The easiest way to check this would be to unplug the motor and check the connector for power: you should have power at the White wire in low, and the DB/O wire in high. Then, yank the relay and see if the slot where the GY.LB wire connects to it is grounded.
It's not likely the MFS because the interval and continuous low and high all share the same set of contacts in the switch. The only difference in modes is the resistance through the contacts and, therefore, the voltage seen by the GEM.
