assuming yours is a climate III USA '87 car, Yes it will hurt... the performance of the automatically-controlled climate controls. Without the sensor, 1/3 of the controls in the feedback loop are missing. No way the system will function as designed. sure, it will still heat and cool, but no luck controlling the temp.

some info is found on my website, The 107SL Source Page... Good luck correcting yours.
