I had the heater in my car stopped working, from a very cold night.
I fixed it by disconnecting the battery for about one minute. I cleaned the posts and the connectors, then reconnected. Presto all fixed. How can I prevent this from happening again?

Hello,

It sounds like the battery is getting weak and losing the HVAC memory. Can you please run this test and get back to us?

and if the battery fails this guide will show you how to change it out.

Please let us know what you find. We are interested to see what it is.

Cheers, Ken

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
