There's also a lot of flex tube running to the vents. Make sure it's intact, not cracked, and connected.

I ran a wire directly from the battery to a toggle switch, to a new blower fuse protected. It blows like a banshee, and makes allot of noise

Clean the A/C evaporator and enclosure. Then, make sure you replace the foam seal around the evaporator coils when reassembling.

Try not to vomit when you see what is in that box.

What is your center vent air temp, high speed, re-circulation on, moving down the road.

Same question, parked rpms at 1500.

I hate it when I get into a customers car to pull it into the shop, turn the key and get blasted by their AC. Gross! You just made it much worse for me Jack.

Ewwww like a B.

Last summer before I cleaned my 90Vert a/c box, I had mosquitoes living in that swamp. They would come swarming out each time I started the car. Ate my *** up for a while. Quick, drop the top and drive fast. Really.

West Nile Virus anyone?

I got you beat on that dude.

My convertible top drain tubes got infested with Bull gnats (the biting blood sucking kind, also known as midges) a couple of years ago.

One day I went to wash my car and all of the sudden I am getting eaten alive by them. There was a swarm of them coming out of the driver side drain and where covering the driver side of the top and simultaneously swarming on me and biting me.

I went inside and sprayed myself down with OFF and them little bitches didn't care and still ate me alive.

Needless to say the car didnt get washed for a while.
