You might be losing A/C R134. You can buy a test kit and new R134 at a parts and the tster will tell you how much R134 you have in your system and you can recharge it at the same time if you need it --Good Luck

Are you saying the engine is difficult to crank, or start ?If it cranks ok but takes a long time to start, the starter is not the problem. You would look at ignition or fuel.

first check to see if the hoses to the heater core are hot. if they are not hot do the following.
Check the valve where the heater core hoses go into the cab, if the valve is good , you may have to wash out the heater core by removing both hoses at the firewall and run some water through the heater core until the water comes out clean of rust and debris.
