Actuator for split climate control (drive/passenger) blows hot when A/C is on and temperature shows that cab should be cool. This has happened several times since I bought the truck.

Thermostat defective and replaced at 5-6,000 miles. Waterpump went at 40,000 miles. Parts were replaced by dealer. Water pump replaced by my mechanic at my cost. 40,000 miles seems like a low amount for a waterpump.

I have a keyless entry and sometimes my rear doors will not unlock with remote or door switches an I have to manually un lock them.
