This listing is for a New Old Stock (NOS) a/c heater control head (Part # 7897076/15-7931).  It will fit the above-listed vehicles with factory air-conditioning.  Please note that the knob and lens styles may be slightly different from year to year.   Also, some Cadillacs came with the digital style control, which is different.  This is the analog style. 

This is a New Old Stock (NOS) switch. That means it was manufactured years ago from GM but never used or installed. It has some light "shelf" wear but in near show quality condition. The box is badly damaged. These are nearly impossible to find NOS, so if you need it, don't let it slip away!

NOTE: These old A/C systems can be very complex. We triple check each switch/unit before we sell it and our warranty rate is less than 1/1000. Purchasing this part will not necessarily resolve an issue you're having. It will only ensure the part you are purchasing from us is not the issue. If you purchase this part and you are still having the problem, the issue likely with another part.
