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.
In the switch
You caint the rain sensor controls the time and delay
If you are sitting on the tractor seat (hood up and side panels removed) the time delay module is on the lefthand side (starter side) of your JD 425. The original module is square and the new one is round.
It is a module under the dash.
The time delay module in this particular model can only be bypassed by an authorised dealer for safety reasons. The part exists to prevent electrocution, so it is prudent to adhere to safety regulations.
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.
I believe J.C. Whitney.com sells a kit to do this
Click on the link below Click on Owner Guides The Owner Guide can be viewed online ( page 391 shows a diagram of Instrument Panel Relay Module # 4 and shows the location of the accesory delay system relay in the module , but unfortunately it just shows an arrow pointing in the direction of the instrument panel and doesn't show the exact location of Relay Module # 4 under the dash )
If the check engine light is illuminated, start with scanning for codes.
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.
Only if you've gotten pregnant. The only thing that controls your period is ovulation (which produces hormones) or birth control that 'mimics' hormones.
