Dianne Posted May 28, 2018 Share Posted May 28, 2018 My front end hit a rather large boulder awhile back, since then AC does not work . I added AC treatment with dye, and AC refrigerant ( polymer free of course ) and it still just blows hot air . Compressor does not engage either now. Rad is fine, no coolant leaked , but are there sensors or connectors up front near the rad that would cause this ? Damage is bumper and the passengers side grill and bumper . Any ideas? 0 Quote Link to comment Share on other sites More sharing options...
eGuru Posted May 29, 2018 Share Posted May 29, 2018 The ambient air temperature sensor is mounted behind the passenger side grill. If the HVAC controller is seeing cold ambient air is available it may not engage the compressor. Did the body shop perhaps forget to replace it or maybe reconnect it? 0 Quote Link to comment Share on other sites More sharing options...
