Nissan is not cool

This bulletin applies to 2007-2012 Nissan Altima sedans and coupes and 2009-2012 Maxima A35 vehicles.

If you confirm that the A/C system is not cooling the cabin to factory specification, and the A/C compressor clutch is engaged, the A/C system is fully charged and the HVAC system doors and controls are working correctly, follow these steps:

  1. Check the A/C system pressures. If the A/C system pressures are HIGH side low and LOW side low, go to Step 2. If the A/C pressures are any other than above, this bulletin does not apply. Refer to ASIST and the service manual for further diagnostic information.
  2. By feel, or with an infrared thermometer, check the temperature of the condenser / receiver dryer outlet tube. If the tube is warm or hot, this bulletin does not apply. Refer to ASIST and the service manual for further diagnostics. If the tube is cool or cold, replace the condenser and receiver dryer assembly.

If the A/C system is not cooling the cabin properly and the receiver dryer outlet tube is cool or cold, replace the condenser and receiver dryer assembly.
