I AM NEW TO THE SITE AND WOULD LIKE TO SAY HELLO FROM ALBERTA CANADA

I have a problem with my 1996 f150 and am hoping for some help. The problem i have is with the heat/air cond. system. The heater works fine and blows hot air as needed in this part of canada at this time of the year but the air cond. compressor is cycling on and off but does not effect the quality of heat. When i run the air conditiong on its own the air conditiong works fine blowing cold air. I have inspected the wiring going to the compresor and it seems fine .Any help would be greatly appreciated

The compressor will cycle with the defrost on to remove humidity. Sounds normal to me.
