270 Ml Problems, Vents,sensor

[MATATMURTON]

Just Bought A 2002 Facelift Model 270ml And Slowly The Faults Appear, First The Seat Sensor "srs" Light Appears,rear Cup Holders Refuse To Pop Out And Now The Stepper Motor, At Least Thats What I Think It Is Has Gone Nuts. Need To Know If Theres Any Advice Out There For The Motor Situation, Turn The Dial To Different Settings, Up, Down To The Feet, Front Vents Etc. And The Flaps Just Rotate For 5 Mins Or So Stopping At Any Position, Can This Be Fixed Without The Motor Replacement....
