Source: smartcarofamerica.com Topic: A/C compressor failure and replacement Models discussed: 453 Solution status: unclear

Problem: 2016 Smart ForTwo 453 A/C compressor not engaging/blowing cold air. Compressor receives power and relay clicks, but compressor does not turn on. Shop diagnosed internal compressor failure and quoted $1600 for replacement.

Solution: unresolved

Key facts: - Compressor receives power and relay clicks when A/C activated, but compressor does not engage - Dealership replacement compressor costs $750 vs $1600 shop labor quote - MB Parts Store (mbpartsstore.com) listed as alternative source for salvage/new compressor - Low refrigerant gas pressure can prevent compressor from running as safety feature - Recommend checking refrigerant pressure before replacing compressor, as winter disuse can dry seals and cause gas loss - Alldata procedure requires lowering rear drive module for compressor access, but user reported engine lowering may not be necessary for replacement
