I have two very annoying problems. One, the windshield wipers will suddenly just stop working, then restart in a few minutes, in no specific switch position. The other is a 420 code that keeps coming up. I have replaced all the sensors [twice], and the cat converter [also twice]. No other codes come up. Any help on either of these would be appreciated.
From your posting, I assume you replaced the O2 sensor before and the one after the cat converter. If you missed one, replace it. Otherwise, you need to look at the signals from these using an upscale code reader to be sure the ECM is getting correct readings. If the readings are a problem, you will need to check the connectors and wiring between these and the ECM (hopefully it's not the ECM itself).
As far as the windshield wipers are concerned, if they work correctly at the full on position, what you are experiencing may be normal - you probably have a rain sensor on your windshield that takes over at lower wiper switch settings. If not, check the connectors at the motor (you may also have a failing logic board in the motor housing).
According to AllData, you don't have to remove the motor to install a new switch. Subsequently, AllData doesn't give direction on wiper arm or motor removal. Here are the only diagrams they give for switch replacement.
Do you turn them on by throwing a lever or by turning a dial? It seems that the switch that controls the wipers may be stuck open.. (metal contacts not seperating)

It could be the screws are loose (at the bottom end of the wipers)
There may be a rubber cap you will need to access the screws. (Also worth checking if the wiper motor is working when wipers are not)
Other possibility, the wiper motor fuse is loose with intermittent connection - locate the fuse box and take out all fuses, inspect them for damage/burn marks and insert them firmly back.

To troubleshoot car windshield wiper problems, you need to thoroughly investigate problems with any of its operating parts. Here are some of the things that you need to check to determine why are your car windshield wipers not working.
Check Wiper Motor The wiper motor is the driving force of the windshield wiper. Feel the motor and listen to a humming sound. If there is no humming, the motor is the problem. Check if the motor is working properly and see to it that its electrical connections are made properly. If you find that the motor is dead and beyond repair, get it replaced immediately.
Check For Break in Connecting Wires The connecting wires of the motor sometimes go loose and that may cause the windshield wipers to stop working. Also check the battery plug connection which the motor has. Connecting the loose wires properly or fixing/replacing the plug might solve your problem.
Check Wiper Switch Another wiper assembly part that can malfunction is the wiper switch itself. Check for switch malfunction and if you find that is indeed the problem, get it replaced from a mechanic.
Check for Bent Wiper Arms Bent wiper arms can cause the operation of the wipers to be hampered. If the wiper arms are bent beyond repair, get them replaced immediately.
Check For Blown Out Car Fuse A blown up car fuse could be the culprit that has stopped the windshield wipers from working. Check the fuse assembly under the dashboard of the car. Replacing a blown fuse might fix the problem of windshield wipers not working.
Windshield Wiper Sprayers Not Working - Things to Check
Sometimes the windshield wiper sprayer stops working which can be very annoying. The washer mechanism is a self cleaning mechanism for the windshield. Here are some of the things that you need to check in case it is not working.
Check Windshield Washer Motor The windshield washer mechanism might have been impaired due to the malfunctioning of the wiper washer motor. Check if its working and get it replaced if it is beyond repair.
Check Windshield Washer Fluid Level Sometimes the washer doesn't work because the washer fluid levels are not filled to requisite levels. Filling in fluid might restore normal functioning.
Check For Broken Washer Hose The connecting washer hose that connects the reservoir to the nozzle, might be broken or worn out stalling the overall operation. Check the hose for leaks and get it replaced.
Check Washer Nozzle For Clogging Last thing to check is the nozzle of the washer for clogging. An obstruction in the washer nozzle might be the reason for windshield wiper sprayers not working. Using a pin, clean the clogged nozzle. This might restore the sprayer to the normal working condition.
