Default Instrumentation Lighting

Hello all, I have a 90' Camry DX with about 274,000 miles on the odometer
and it runs great still! But, the lighting for the instrumentation is really
poor. I can hardly see the gas gauge. Does anyone know if it's possible to
replace the bulb or will I have to purchase an entirely new panel to have
better lighting. Also, the fan speed control does not work until I select
the second from the highest setting. Is there a fuse that needs to be
replaced that is easy to get to? I will have to have my AC checked as well.
When I hit the AC button, the light comes on but no cool air comes out.
Thanks in advance for any help given.

And I was told I present hard problems!

Actually, these aren't hard, just not easy.

First, you can replace the bulbs in the instrument cluster, Before we do
that, are ALL the guages dim? If so, it may be the rheostat, or the
'dimmer' control, which is almost as difficult.

Rempove the knob, and you will see a retaining nut. Loosen the nut and
push the shaft through the dash. It's a long stretch; I hope you have long
arms!

There are a few things you can do. Replacing is the easiest but most
costly. You can probably get one from a boneyard cheap. I think they are
the same for 99% of Toys. But I would try this first. Go to Radio Shack or
another Electronics supply store and get some "Contact c;eaner". Spray
inside the can liberally and move the shaft left to right about 100 times,
and spray again (well, maybe not 100, you get the idea!). Spray again.
move it again and let it dry.

BEFORE we go to the trouble of reassembling, in a garage or somewhere you
can see the guage cluster when it's lit, turn on the lights and turn the
shaft. If it brightens up, we've solved this problem. If it doesn't get as
bright as you recall, you need a new one. As you can now see, all you have
to do is unclip the connector and clip on a new one.

If this didn't solve it, I would go back to the boneyard and get a whole
instrument cluster. Call around, they'll range from $25-100! Since this
appears to be global, I don't believe it's the bulbs, but a trace on the
printed circuit that is going bad.

To remove the intrument cluster, lower the wheel all the way down if you
have tilt. This will be a LOT easier if you loosen the two bolts holding
the wheel to the dash; support the sterring column when you do this!

At the top of the instrument cluster you'll see 3-4 screws holding the
shroud in. Remove these and carefully pull the shroud out. Now you'll see
a number of gold/brass colored screws holding the instrument cluster.
Remove these and pull the cluster out carefully! When you get to where you
can see behind it, remove the connectors from behind the cluster. They
will only install one way, so no need to mark them.

The bulbs are located in the 'twisty' things; to remove them turn them to
the left, and to the right to install.

Depending on which type you have, you MAYbe able to pull the bul and
replace it, probably not. You'll need whole new asseblies, bulb and
carrier from Toyota or AutoZone, etc. You CAN pull the bulb and replace
it, but that means the wires may not make contact, and only Gumbies like
me use this method! Install the bulbs or swap the cluster as required.

For your fan, I hope you're a contorsionist! What we're going to have to
do here is crawl up under the passenger's side dash, behind the glove box.
You'll see a round black assy with three 10mm bolts. This is the fan
blower. You have to get in there and loosen the bolts to get the fan motor
out; it can be done without removing the dash if you have the patience of
Job (I don't...this is an aggravating job!). It helps if you have a short
socket or a short socket and a swivel adapter.

Pull the bottom off once you get the bolts out. You should see three
pieces of wire that look like springs. One or two of these have gone bad.
You can either replace the resistor pack, or just get another whole assy
from the boneyard (from a low mileage car!) and replace it. You're
probably due for brushes inside the fan motor, if this has never been
replaced; thisis a really tough job, and although I do it, you're bettr
off replacing the whole fan assy. Reasemble opposite the way you
disassembled.

As for your AC, I have now gotten to where i roll my windows down. On a
car this old, you'll wind up replacing the whole AC system for $800-1400.

Good luck! Hope you're not doing anything tommorow and part of Sunday!

First of all I also have a 1990 camry. i replaced the bulbs in my cluster
and its actually very simple!! there should be 5 screws that hold the
plastic around the cluster. then 5 to hold the cluster in after the plastic
is off. The number for the bulbs is 194. can find em for about 9cents at
napa..
As for the air i retro fitted myne to convert it to R-134a freon and nowmy
air works great!! can buy a retro kit for around 100$ at autostore. then wut
ever the price of freon is. The car should take about a pound and 6 ounces
of freon....
