2008 Buick Lacrosse, wiper delay problem

In delay wiper mode, my wipers work ok and then once in awhile they will stop and the wiper will jump about 3 inches and then pause for about 10 to 12 seconds and then make two passed and then they will be ok for awhile. My wipers do the sme thing. They will be working fine, then Jump about 3 or 4 inches. Then do two passes before returning to normal.

Sounds to me like a weak windshield wiper motor.  My 92 sable did this.  Replacing the motor solved the problem.

Winshield wiper delay intermitent module making noises


The wiper delay is in the steering column. It's a small box about 2 x 2 inches with a wiring harness attached. With the testing procedures I found below, you should be able to figure it out. I found wiper delays on eBay for around $10 to $20. Good luck.

WINDSHIELD WIPERS CHEROKEE, COMANCHE & WAGONEER 1. POWER INPUT Remove circuit breaker. Test battery side of circuit breaker. If battery voltage is not present, repair open to splice. Test across circuit breaker terminals. Tester reading should be zero (0) ohms. If not, replace circuit breaker. 2. GROUND Connector A unplugged. Test terminal G. Tester reading should be zero (0) ohms. If not, repair open to ground. 3. INTERMITTENT WIPERS Ignition switch in ACCY. Remove delay module and plug connectors together from the module. If wiper operate in LO and HI speed modes and mist (washer) is working, if wipers and mist operate, replace intermittent module. If not go to step 4. 4. WIPER/WASHER SWITCH Ignition in RUN, wiper switch position as indicated, back probe switch side of connector A for standard, connector B for intermittent: Test connector terminal E-wiper switch in LO and mist/intermittent. If battery voltage is not present, replace switch. test connector terminal C-wiper switch in HI. If battery voltage is not present, replace switch. Test connector terminal F-wiper switch to OFF. If battery voltage is present until wipers stop and then voltage drops to zero (0), system is working fine. If this does not occur, replace switch. 5. INTERMITTENT WIPERS Connector B unplug. Test across terminal A and D while rotating switch from minimum to maximum delay. If tester reading is not between 0-500 ohms, replace switch. Test across terminal A and G while rotating switch from minimum delay to maximum delay. If tester reading is between 0 and 500 ohms, replace wiper module. If not replace switch. 6. WIPER MOTOR Ignition in ACCY, wiper switch position as indicated, probe connector D. Test connector terminal 1. If resistance is no zero (0) ohms,repair open to ground. Test connector terminal 4-wiper switch in any position. If battery voltage is present, replace motor. if is not repair open from fuse panel. Test connector terminal 2-wiper switch in LO. If battery voltage is present, replace motor. If not , repair open from wiper switch. Test connector terminal 2-wiper switch in HI. If battery voltage is present, replace motor. If not , repair open from wiper switch. Test connector terminal 5-wiper switch OFF with voltmeter connected. If battery voltage is present until wipers stop and then voltage drops to zero, system is OK, replace motor. If not, repair open from wiper switch.

Replace the "pulse board". It sounds like it has a short. Most parts houses have them at a reasonable price.

2002 Buick Regal wiper motor parks wrong on dlay


remove cowling under hood to expose wiper motor linkage. You have to try it many times but the linkage may not be attached in the correct arc position. Trial by error.
