Which fuse? In your glovebox manual it will give a name or it's on the cover for the fusebox. What amperage is the fuse? 10, 20?

Hello, in looking for the cause of a fuse blowing regularly I would ask, did the system in question work ok since you have owned the vehicle, and if so, did something change when it started to pop fuses? Such as the installation of an electrical component, a stereo system for example, or a new remote start system, anything that was added to the electrical system. If this is not the case, then most likely there is a failed or shorted component in the HVAC system, these systems are very complicated, some with multiple sensors, autonomous switches and actuators, etc....etc. This would require testing by a qualified tech with proper instrumentation. Good luck, it would be interesting to know what you find as the actual cause.
