Causes

Failed or sticking wiper relay
Blown fuse or poor fuse connection
Open, shorted or corroded wiring between BCM, relay and wiper motor
Poor ground at wiper motor or relay module
Faulty windscreen wiper motor drawing excessive current or mechanically jammed
Faulty BCM or relay driver inside BCM

Symptoms

Wipers fail to turn on when switched on
Wipers won’t turn off or stay stuck on
Intermittent operation of the wipers
Audible relay click with no motor movement or no click at all
Reduced or no wiper park function (wipers not returning to resting position)
Fuse blows repeatedly when wipers are operated

What to check

Read stored fault codes with an appropriate scan tool and record freeze-frame data
Visually inspect relay, relay socket, wiring harness, and connectors for corrosion, damage, water ingress or loose pins
Check relevant fuses and fuse holder for continuity and secure fit
Attempt to operate wipers and listen for relay clicking at the relay location
Backprobe relay coil/control pins while operating wiper switch to confirm control signal from BCM (12V or ground depending on design)
Measure battery voltage at relay power feed with wipers off and during operation (should be close to battery voltage)

Signal parameters

Supply voltage: ~12 V nominal at relay power terminal (should remain near battery voltage under load)
Control signal: switched +12 V or switched ground from BCM to relay coil when wipers commanded on (verify via backprobe)
Relay coil resistance: varies by relay model (typically tens to a few hundred ohms) — compare to service spec or identical relay
Typical wiper motor current: commonly ~5–15 A depending on load; stalled/jammed motor may draw significantly more

Diagnostic algorithm

Connect scan tool, read/record B1095 and any related codes; clear codes and attempt to reproduce.
Visually inspect relay, relay socket, harness and connectors for damage/corrosion; inspect fuses and fuse holder.
With accessory power on, operate wipers and listen for relay click. If no click, backprobe relay control coil pin and verify BCM command (12 V or ground) when wiper switch is operated.
Check battery voltage at relay power pin during operation; significant voltage drop indicates poor supply or high resistance connection.
Check ground continuity for relay/motor circuits to chassis; repair any poor grounds.
Measure current draw at the wiper motor with an ammeter while operating; high current suggests motor or mechanical binding—inspect/replace motor or linkage if needed.
If control signal from BCM is correct and supply/ground are good but relay does not switch, replace relay and retest.
If relay replacement does not cure and BCM does not provide correct control signal, perform BCM communications and module tests, check for software updates, and consider BCM repair/reprogramming per manufacturer procedure.
After repairs, clear codes and perform full function test, including park and intermittent functions.

Likely causes

Faulty/unseated wiper relay
Blown wiper motor fuse or poor fuse holder connection
Open or shorted control wire between BCM and relay coil
Corroded relay socket or connectors
High current draw from a failing wiper motor causing relay to trip or weld contacts
