No change of temperature and blower doesnt blow when turned on.

 

The infamous blower motor connection is burned. Requires new connector which a vendor here sells and possibly a new blower motor. Theres lots of threads on this.

 

It's a cheap piece, I had it replaced before, it was something around $5 not sure, but you gotta splice and connect about 10 wires if you DIY. If you listen to the dealer or whoever tells you what you'll have to replace, it might be around 100 but you don't need that whole wiring system, just the piece that is burned out.

 

get the NEW UPDATED with longer wires --power connector for the blower, at acura $20
may also need a new resistor, located on blower motor mounting plate
visual under its shield will usually tell it fried

start with visual ck: under glovebox exterior edge- see the white connector- look at its underside too for blackening of connector,, or melted wires

 

you did ck the cabin fan fuse right? if something else fails it may blow the fuse
