Left park brake fault. Contact dealer for service.
Hope this helps.

You are getting a motor error code. Check motor wiring and connection to the main control box. Motor may have gotten unplugged when changing the batteries.

thats a right motor fault, check connections first and cableing

This is a common problem with the M91 when the motors are more than several years old.
An error code of 4 flashes indicates a right motor fault. The right motor could have a short or open circuit, or a bad connection.
Check the right motor, connections and motor cable visually and with a voltmeter at the connector. Look for cuts, nicks and breaks in the wiring and for grease oozing out of the gearbox. Flip the seat back and remove the top cover. Disconnect the black square right motor plug and check the resistance across the red and black motor wires using a digital volt meter. 0 to 1.6 ohms is OK, anything out of this range is suspect.
If the motors are more than 3 years old, you should consider replacing the motor/brake/gearboxes as a pair, left and right. The motor/brake is about $650 with the motor/ brake/ gearbox assembly about $1,000 per side. Labor is 2 to 3 hours total. I usually replace the brake/motor/gearbox as a complete assembly to avoid future problems. Hope this helps.

With the M91 the click you are hearing is the electric brake solenoid engaging and disengaging the electro mechanical brake. The display blinking probably indicates a brake solenoid fault code and right or left motor. Try working both brake levers back and forth listening for and feeling for smooth action. If the levers are bent and the brakes are not working a motor replacement is necessary. If you can identify the fault flash code you can determine which brake or motor is the culprit and use a DVM to verify the component failure.

This is a common fault often caused by low battery voltage, before you start taking expensive actions with the park brake modules etc get your battery checked for 100% efficiency.
Hope this helps, good luck.
