Your brother's mechanic may be correct but you may want to double check if you have a bad flap which opens / closes the access of coolant thru your heater hoses to your heater core. This component is called an actuator which may be defective.

Temperature gauge fluctuates and the heater blows cold air


Definitely check your fluid level in your radiator. Top it off all the way. I've seen that happen multiple times on cars that were low on anti-freeze. If that doesn't work try replacing your thermostat. It's cheap and the easiest place to start if topping off the fluid doesn't get you fixed up.
