hey guys i have a 97 4x4 in the morning when my truck gets to running temp and i turn the temp from cold to hot it stays cold i might have to turn it from cold to hot 3 or 4 times before it goes to hot had the same problem with the a/c yesterday turned it to cold and it got cool but not ice cold had to turn it to hot about 3 or 4 times before it stayed ice cold. think the accuator is going bad or the ****

 

1. Cracked temp control ****

2. Blend door/actuator
