A/C Service — Mercedes in Malaysian Climate
Malaysia's year-round tropical heat makes A/C performance a top priority. Common Mercedes A/C issues: blower motor failure (W204 — replacement), clogged cabin filter causing poor airflow, evaporator mold from Malaysia's humidity (musty smell, common on vehicles with frequent short trips). Gas recharge (R134a or R1234yf depending on model year) every 3–5 years or when cooling weakens. Always pressure-test for leaks before recharging. G-Class and GLE with tri-zone climate control require specialist knowledge for accurate diagnosis.
