I have no problems with my installation...except the electrical hookups do
not match the schematic he supplied later (perhaps because he used the
previous switch, I'm not sure). He was happy to help up (two years later) to
that point, and since I did manage to get it working I haven't taken it
back. When working, it uses the additional ashtray vent and the two freshair
vents and helps the front out quite a bit.
Overall I would recommend it, if you want cool air in front.
