the heater blows are but isnt hot

Hello, one of two things is happening: The engine may not be getting to the proper operating temperature, which means the coolant will not be hot enough to generate sufficient heat for the heater. This can be due to a few possible causes, most notably an engine thermostat that is sticking open. The climate control system may not be working properly. There are controls to change air temperature from hot to cold and blends in between. If the controls are malfunctioning, then you may not get the desired temperature of air output. www.repairpal.com/repair-shops That link can find you some shops near you to help diagnose the concern.
