Trying to figure out how to remove the fuse box cover on a 2005 chevy impala i reached inside the hole on the panel and cant seem to find a release. I also tried just bute forcing the panel by pulling on it and can't seem to get it to budge. Any suggestions the manual is not very helpful.

Try this..At the driver's seat open your car door all the way then look at the dashboard end. Pry off the plastic cover...the diagram should also be at the back of the cover.

I don't know about the rear defrost, but there are 2 fuse boxes inside the car. Just inside the doors on the far sides of the dash. The covers sit between the dash and the doors. There are holes to stick your fingers in, and pull the covers off.

The fan issue, may be different then the prob. I had, I didn't have speed 1 or 2 on mine.
I don't remeber what the part is called, but it's some resistor board deal, that sits up under the dash on the Pass. side, right up against the firewall, it's a pain to get the new one in, once the old one is out though, so be careful not to crack the board. Ask a dealer, they will know what it is. I think it costed me like $30.
I hope that helps.

Pricing vary, depending on where you live and if you want it done at a dealership or at a local shop.It would be about 1hour of labor +price of the hose+power steering fluid. Dealer charges about $70.00 an hour.
You can call the dealer ask how much to change the hose. Also a local shop can gave you an estimate.
