On my 1999 Civic EX, the fan makes squeaky noises the till half speed then the sound goes away.
How do I fix it? Where/how do I get to the fan to clean it?
There's no filter. After unplugging the connector and removing three screws, the blower motor drops straight down from behind the glove box. It's common for the blower to collect debris, such as leaves, so check that first.
