lastly it is possible the temperature control door is somehow not holding at the higher speeds.if the cabin filter was not used this is a good possibility as debris will damage the air box componets
the fan speeds work fine. it is the air temp that gets hot when u turn the fan to 4 or 5. When you say cabin air filter do you mean engine air filter?
