Hi everyone. I think this is the correct section for this. If not, please move it accordingly.
A couple weeks ago my heater started acting up. It wouldn't blow hot air unless I was at a minimum of 2k RPMs. If I was at an idle it would still blow, but it would be cold. Now, it won't blow hot air at all. The coolant reservoir was empty, so I filled it up to under the max line. Turned the car on and let it sit awhile while running and still no heat. With the engine running I looked at the reservoir and saw no fluid moving. With the engine only running about 10 minutes, I popped the cap off the radiator and saw no fluid inside. I saw no circulation of anything.
What could be causing this issue?
