Heater didn’t work this morning. Makes a gurgling noise when A/C is on. Found that coolant was low but can’t find the leak. Any suggestions?

Hi, I'm Dan. The easiest way to check for leaks is to use a pressure tester. I've attached a link to the procedure to do this.

Good afternoon,

Besides making sure the coolant level is correct, I would also make sure there is heat when the level is full.

If it is, then you need to find the leak and then repair it.

If it does not, then you need to check the thermostat and the blend door motor for proper operation.
