Heater blows cold front and back


You could be low on coolant - better check.

Your heater core might be the problem:

I have a 1993 Acura Ledgend. For some reason my heater does not continue to blow hot air, it does for a few minutes and then begain to blow cold air. It does this often now. It works and then it blows cold...


first check to see that you coolant level is full, check it after the engine has cooled down,so there is no pressure in the system. otherwise you possibly have a head gasket in the early stage of failure

Have you checked the coolant level? If it's low, it will result in diminished heat, and could be the problem.

Heater doesn't blow hot air


First check the coolant level in the radiator. Check your heater core hoses on the firewall underneath the hood. Let the car come up to temp. and feel the two hoses. If only one of them is getting hot you may have bad heater core or a bad heater control valve.

check fluid level if full remove rad cap when car is cold and run while looking at fluid in rad if it is circulating you should see it moving if it does'nt move after car warms up thermostat needs to be replaced also check to see if fan is working properly and check the reputation of your mechanic some are not always honest
