This is a complex wiper circuit ! The place to start would be to check for DTC'S - diagnostic trouble code's .
DTC B3715, B3716, B3717, B3718, or B3719
The body control module (BCM) controls and monitors the state of the ON/OFF wiper relay control circuit. When the windshield wiper switch is placed in to a low speed setting, a signal is applied to the BCM. The BCM then applies battery positive voltage to the coil side of the ON/OFF WPR relay through the relay control circuit. This energizes the relay, allowing battery positive voltage from the FRT/WPR fuse through the switched side of the ON/OFF WPR relay through the HI/LOW WPR relay and to the windshield wiper motor. Ground is applied at all times to the coil sides of the wiper relays and the windshield wiper motor from G105.
• DTC B3717, the BCM detects a low voltage level on the supply circuit of the wiper micro relay for 1 second when the relay is energized.
• DTC B3718, the BCM detects a high voltage level on the supply circuit of the wiper micro relay for 1 second when the relay is de-energized
Your best bet mite be to take your vehicle to a qualified repair shop !

Visit the on-line store, know as reliable-store, they have the repair manuals. I'm sure you will get the solution of your problem.

No wipers at all , hi , low , delayed ? You really need a factory scan tool to diagnose this problem , there is a lot involved ! The switch , BCM , wiper relay , an wiper hi relay ! With a scan tool you would be able to access data parameters in the BCM - body control module . When you turn the switch to turn on the wipers , that's an input to the BCM , the BCM then energizes the proper relay in the under hood relay box . Turning on the wipers ! Plus there could be trouble codes stored in the BCM pointing to a problem .
Low Speed Operation
When the wiper switch is in the low speed position, ground is applied through a resistor internal to the switch and the wiper switch low signal circuit to the body control module (BCM). In response to this signal, the BCM energizes the WPR relay by applying battery voltage through the wiper relay control circuit to the coil side of the relay. This allows battery positive voltage from the WPR fuse to flow through the switch input side of the WPR relay and out to the switch input side of the WPR HI relay. Since the wiper high relay is de-energized and its switch contacts are normally closed to the low speed control circuit of the windshield wiper motor, the motor will operate at low speed.
Wiper motor low speed operation and the WPR relay can also be commanded ON/OFF by using a scan tool. Refer to Scan Tool Output

03 Ascender but what is and Intrigue? (apples and oranges, diffr)
built at:
GM Fairfax plant in Kansas City, Kansas,
2000 Oldsmobile Intrigue in wrong forum, my guess.
why not post the symptoms first. dead on all speeds, and does
it have the intermittent option?
why assume there is a relay?
would not the fuse be first.? if dead?

wiper not washer is FUSE WPR 25amps.
does the wiper work on WASH mode, 1 swipe. (trick 1)
does the wiper run on any speed? (sop)
no and no.the fuse is blown
to test fuse, use a voltmeter.
Keyon
12vdc on both sides of WPR fuse, is a good fuse. no lies, no guessing. fuses that look blow are blown but some that look ok
are in fact blown (due to hairline cracks only mini mouse can see)

there IS NO RELAY. soRRY, i can add one if you like (LOL)

here it is.

HI
HOW DO Reset Factory SUPRA LCD TV 32 PLZ?

The WPR fuse is for the wiper and washer system. It is a 25 Amp fuse that powers up the WIPER HI relay, WIPER relay, and the WSH relay.

i nned by back light inveior borad how to by pleas send me web add and company detals

motor shot

The car should be worth no more than 2000. There's no such thing as a celica supra, it's either a celica or supra. Don't be fooled

sounds like the starter is bad
