The wiper circuit that controls (in this case that opens the ground circuit of the motor)the motor is staying closed to ground...it needs to be open when in delay mode...so that the delay circuit can control the opening and closing to ground. OR the delay circuit has an open circuit...burned up capacitor, relay, etc. Or it could be a stuck parking switch...which should open on in park mode...however the wipers would stay on until you turned off the wiper switch. Also, old cars up to 1980 or so...used ground type switches whereas new cars use powered switches and relays to latch the motor to ground.
Bad switch? stalk bad wiper motor? bad low speed winding
most likely the switch is bad, or the wire plug has a bad connection
On my 1995 Ford Explorer , two of the intermittent wiper positions stopped working and I would have to push the windshield washer squirter button 2 or 3 times before fluid would squirt . It turned out to be the multi - function switch inside the steering column ( turn signals , hazards , wipers , high beams etc . ) A Ford dealer changed it quite a few years ago and I've had no problems since
The multi-function switch inside the steering column has the turn signal lever and hazard lights button extending outside of the steering column it operates - turn signals - flash to pass - high beam headlights - windshield wipers ( on/off ) and intermittent speed settings for the wipers - windshield washer fluid squirter button
The resitor is probably burnt out on the high mode
windshield wipers have different kinds of speeds such as the ones listed below:Low speed: Low, Intermediate,HighNormal speed: Low, Intermediate,High (recommended speeds for rain and clean up)High "" hope i helped
The wiper motor can be replaced reasonably easy, however your particular problem is usually caused by the circuit board that controls the wiper motor and the delay cycles, retraction, etc. The board is also quite cheaper than the entire wiper motor. It is also called a wiper pulse or relay board and can be found online from around $25 and up. The electronic board plugs into the wiper motor, and the electric cable plugs into the circuit board.
General Motors had a recall on some of the delay modules. Call the dealership and give them your vehicle identification number and have them check to see if it applies or if there are any that have not been done. It is free and it does not matter if you are the 5th person to own it. A RECALL is FREE, a technical service bulletin is NOT.
There aren't any switches to check/replace i.e. wiper switch, wiper relay therefore it must be a bad motor.
I have a 94 caprice that does this. Apparently it is either that speed only on the wiper motor that has a problem or the relay for the high speed may have failed and the motor may be ok. As it is a noncritical issue I haven't worried too much about it. If I find out more I will update this.
try checking the switch
If the motor works on high, or any speed, then it's fine. Switches and resistors control speed and delay.
