My 2003 Wira 1.3 A/B also not spared from problem but most of them because of wear and tear.
The rear absorber not kong but replace it with APM Performax after 4 years. The small A/C sensor also replace with new unit after my car develop some serious engine problem which cause the engine die suddenly in the middle of the road. Luckily not meet with any accidents.
Power window still like new, no problem...since I'm a lone driver, no other itchy hand other than me.
Major repair done last moth because of timing belt snap suddenly and need to do top overhaul. End up rm650.00 fly just like that replacing MMC timing belt, aircond belt, 1 rocker arm, 12 valves...all new, the engine rejuvenate after all complete.
So far no problem with the aircond. Still cold.
