The wiper motor is well overdue servicing/replacement. The wiper delay works with the self parking contacts and it sounds that they are fouled/worn out. The slow running would suggest worn motor brushes/motor and gearbox bearings/drive rods and bushes. If you can't service the motor yourself, you should be able to pick one up from a breakers or take to an auto electrician who will refurbish or provide an exchange one
where is the wiper switch located on a 85 el camino w/pulse wipers,the car has tilt wheel
the wiper delay dodule is located under the hood on the firewall. you will see the motor for the wipers and you take that cover off. it has 3 torx bit screws that holds it on. under this cover is a circut board. that is your wiper delay module.
convert the electrical resistance signal from wiper switch to electrival power to wiper motor (for delay wipers)
In the switch
The delay system may not have anything to do with the switch. It depends on the manufacturer but the delay system maybe part of the wiper motor assembly...or the delay is sometimes located in a separate module located separately from the control switch.
perhaps the wiper switch is broken and needs to be replaced.-- The delay part of the Switch.
I'm figuring that this is the same as my 1999 town and country, and I just replaced the wiper switch.. It was easy, and it cost 76.00, and it also had NO effect on the operation of the delay in the wipers. Incidentally, I was trying to fix the delay - What my vehicle does is the delay will work about 4 times, then the wipers "jump" slightly, and the delay no longer works. you have to cycle the wiper switch on and off to get them to go again. Good luck!
depending on the make and modle, could be wiper module, linkage,
It's on the wiper control switch on the multi-function switch.
an intermittent wiper has a built in delay , wipes once then waits and wipes again, speed depending setting you put it on, non intermittent wipers dont have a delay and keeps going until you turn them off, no waiting, wipes, hits bottom and wipes again right away
everything is built into wiper motor including delay timer. there is a fuse you must check no relay.
find you a donor vehicle like a Monte Carlo,if you have a turn signal switch with a dimmer switch combined then your in luck ,the Monte Carlo has the wiper with delay,dimmer and turn signal switch all in one .if the wiper switch is on the dash then you might look twards a switch and wiper motor from a caprice classic, the wiper motor has the delay board installed on it just plug and play.don't foget to hook up the green pulse wire to the single terminal under the washer pump,this can be done because i converted my 71 ss chevelle to delay system,only mods was mounting the switch but i did it without drilling or cutting my dash.
