right underneath the fog lights there is this wheel that you can roll up and down. l can not figure out what the dmn thing is used for. can anybody tell me. l do not have a drivers manual.

please answer if you truly know.

Another question, my rear window washer sprayer does not work but the front 2 sprayers do. what can l do to fix this problem. my window washing fluid is full!

l am not a tiburon owner but l am guessing the wheel is for adjusting the dash lighting, try turning it with the lights on at night or when it is dark enough to see the lights on the dash

The wheel is most likely the dimmer control for you instrument panel lights and the rear window washer is switched separately from the front ones. Look near the rear wiper switch for the rear spray switch.

Yep, The wheel is the dimmer control for you instrument panel lights.

Hold the rear washer button for like 30 secs, l think the hose drains out and it take a while for the hoise to fill up again, if you do not use it often.

for ur first question it is what we call the rheostat it adjusts the lights on ur dash at night when u can see them at least thats what it sounds like ur talking about for ur second question u have two pumps one for the front & one for the rear if u look under the car in the front passenger area in front of the wheel there will be a couple of plastic screws take them out then pull the inner fender panel away (i use a bungee to hold it out the away) look up in the fenderwell u will see ur resivoir & the two pumps. To distinguish the two l unplug one of the pumps & then try the front sprayer if it sprays then u unplugged the right pump now when u disconnect the hose feeding the washer fluid up to the sprayer use a little hook or screwdriver just break the seal before u pull it off so u dont damage the hose after that it should be ready to come out u can either catch all ur washer fluid(it will start pouring out in a stream through the pump)or take ur screw driver & wedge it between the bottle & pump & pop it off if u decided not to wait for all the fluid to drain it will gush out once u pop it out. The rubber seal on the bottle usually stays in but if it pops out just pop it back in make sure its seated right the install the new pump put it back together the connecter can only go on one way & thats about it if u do not wanna do it it is at 100 bucks at a dealer

those are reasons to push your hyundai to the junkyard

That wheel is the dimmer switch for the dashboard lights
