Having the same problems except my wipers won't park. My Jeep mechanic told me I needed to replace my wiper motor - he pulled the wiper delay module and bypassed it to prove it wasn't anything to do with the module. Have you solved your problem yet? I'll let you know if I'm successful after replacing the motor. On my '90 Cherokee, the wipers only had one speed, would not park. I had the motor and delay module replaced - still did not work. I then had the linkage replaced with a rebuild - works perfect now! I'd check the linkage.
The fuse, if not, then the switch, then the motor, but by then you will also need a test light and/or a DMM.
Check the fuse
Check the oxygen sensor. My 1995 Grand Cherokee stopped stalling while driving after it was replaced.
Check for a broken wire in the harness going to the drivers door.
When my jeep cherokee alternator went bad, the check engine light came on and I didnt have a clue what was going on until my volt guage was reading in the red zone. When I replaced my alternator, the light went off. So in my opinion i wouldnt consider the check engine light as a alternator light.
check the fuses and relays
i would check if you have power to the motor from the switch
It might be tine for some new wipers on the car. You might also need to check the connection of it to see if that part needs to be replaced.
it may not be grounded. correctly. did you check it before you put it on? check with volt meter see if it is getting power. also it maybe that the rod to the wipers are jammed check them out.

Generally, if the motor is working on windshield wipers, the problem is electrical. Check the fuses and the wiring to see if something needs replaced.

If the problem started after you replaced a fuse, you need to check that the fuse is good and installed properly.
Check the motor for the wipers.
dose the electric fan run if not check the relay if it runs check the water pump
The two first things to check are the fuse and the blinker capacitor. Both can be replaced very inexpensively.
