HVAC System is Not Cold Enough (Adjust Temperature Control Cable)

Some customers may comment that the HVAC (heating, ventilation and air conditioning) system does not get cold enough.

This condition may be caused by a misadjusted HVAC temperature control cable.

Adjust the HVAC temperature control cable using the Temperature Control Cable Adjustment procedure (SI Document ID #841682). The inspection and adjustment procedures are very easy and should take no more that two minutes to complete. The key points to the cable adjustment are to make sure that the temperature control knob is held in the full cold position, and the temperature control lever is held in the full rearward (cold) position. The purpose for this bulletin is to make sure our dealers are not overlooking this simple adjustment that has a huge impact on the HVAC outlet temperatures. If the HVAC temperature control cable does not repair this concern, perform the Air Conditioning (A/C) System Performance Test (SI Document ID #839856) and repair as necessary.
