Hey guys I have been having this issue for a while and I don't know what's causing it I thought possibly the bmr or a fuse went out but I don't know what is wrong with it there is a noise that happens when I turn my ac on and off under my glovebox i think it's the blower motor regulator activating but I'm not too sure any insight on my issue would be greatly appreciated

sounds like the blower motor, to test make sure the blower motor switch is in the activated position measure the voltage with a multi-meter make sure its getting sufficient voltage and ground if it is then the motor is worn internally, is it making a Loud rattling, thumping, clanking or banging noise?

How do I know which one is the positive and negative prong also no it's not making any noise I just looked up something and someone said to take the blower motor out and check for rust so I'm about to check that right now because there was wet spots under the blower motor on the cover

There isn't a clanking noise or rattle or anything like that it just sounds like it's activating when I turn it on I don't really know how to explain the noise

strange if the blower motor is gone there is going to be very noticeable noise. it could be the bmr, as for the noise you are hearing im not quite sure.

Alright I'll probably buy a new one and throw it in and see if that fixes it
