In terms of yours being "toast" is it completely dead? Or does it look like mine where the housing looked like s*** but the light still worked - albeit somewhat dimmer and yellower! There are a few options you can choose.
I had to do this repair a few years ago as my passenger side had rust in it; I replaced both because the driver's side did not look that much better! Luckily, the light itself still worked so I only had to order the housings.
If memory serves me correctly, there's a bolt or screw that holds one side of the housing on and a tab that slides into the side of the bumper housing. This is for my 98 at least, I don't know if they changed the design with the 2003 facelift (theoretically they shouldn't have if the part numbers are the same from year to year).
Just unscrew it, unplug the bulb from the housing, and pull the the entire thing out from the front. This picture shows the tab, but the screw/bolt is on the opposite side.
I noticed the replacements that I got from Toyota had redesigned light bulb sockets to help with water intrusion. Three years later and they still look brand new.
I checked with a Toyota parts site that I frequent for pretty much everything. Replacements from
www.midatlantictoyotaparts.com were $136.99 for either side housing (the list price is around $182.00). This price is for the housing
ONLY which was all that I needed when I swapped the housings out.
Part numbers for the
housings: $136.99 per side ($182.65 list price)
- FRONT LEFT: 81221-60042 (Replaces part #: 81221-60040 and 81221-60041)
- FRONT RIGHT: 81221-60122 (Replaces part #: 81221-60120 and 81221-60121)
The
ENTIRE foglight includes the housing, the bulb socket, and the bulb.
Part numbers for the
entire foglight: $175.93 per side ($234.57 list price)
- FRONT LEFT: 81220-60042 (Replaces part #: 81220-60040 and 81220-60041)
- FRONT RIGHT: 81210-60122 (Replaces part #: 81210-60120 and 81210-60121)
The part numbers for the housings are all the same for the 100 series model years according to their site. For the 2005-2007, they do not have any
entire foglights listed.
I'd be wary of the
ebay lights only because of poor quality on some units and after reading up on horror stories of people who bought headlight/taillight housings and having them crack/leak/fog/fail within a year.
Hope this helps,
Rich
