Re: air filter message and cooling fans
There are actually 3. If you are looking at the back of the TV with the panel off, there is a big one on the right next to the silver lamp box. Just to the left of it is a black square tube that the lamp shines into, there is a fan attatched to the bottom of that black square tube, the third is further left from that tube, attatched to the powersupply and mainboard cage. You'll be able to see that one easily enough. Don't use compressed air, it just blows stuff around. Use a vacuum with the brush attatchment to clean what you can. If you don't have the back panel off, you won't mess anything up by removing it, just take out the gold screws and you'll have decent access to all the fans. The second on will be a little tricky to get to. Don't fumble around with the vacuum hose, be careful and you won't accidentally unhook anything. There are no actual filters beyond the black plastic grating on the outside of the TV. If you need more help, I can email you photos.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Check and clean the filter if found to be dirty. It is usually behind a decorative panel below the cold air output grates (when the cold air is on the top front).
The filter is behind the large, rectangular, slotted front panel. The evaporator coil is behind the filter. The fan behind the evaporator pulls the room air through the filter and evaporator coil where it is cooled and dehumidified. It is then discharged through the grates on the top of the front.
Direct the airflow from the unit up and away or left / right to prevent the cool air from being drawn in the front of the unit (this is where the thermostat sensor is located). Use the highest fan speed to help force the air away from the intake, too. Inspect the condenser and evaporator coils (condenser is outside and evaporator is directly behind the filter. Clean if dirty or icing over. Be sure to install a filter if none was present. There are products made specifically for cleaning between the fins of the condenser and evaporator coils. Use them only as directed.
If these suggestions do not work, you may have a problem with the thermostat, refrigerant level, condenser or condenser fan.
If you have the user manual,read it first.It will show the reasons why those messages are poping up.Temperature sensors are located on the vents which gives you the problem messages. Usual problem is that the vents cooling your system is blocked preventing the air to cool your heating lamp.If you want to do service on your own(try your warranty first,opening the unit voids the warranty) you can unscrew the covers yourself.Unplug the unit first.Get a clear tape and as you remove the screws,tape the screws near the holes you got them from to prevent confusion upon rescrewing the covers back.Locate the vents filters,usually found on near exhaust fans and locate another one with a foam and screen near a smaller fan.Blow or get a smaller powered vacuum to **** dirts out.Re-install the foam and screen filter the way you removed it,be sure to observe the connector for the fans.
This car has a relay module that contains a few relays internally and cant be serviced the relay box must be replaced, the relay box module that contains the fan and ac compressor and fuelpump relays is located under the air filter box, remove the filter box and you will see the relay module bolted there. hope this helps.
the cooling fan relay that you refer to is near the air filter housing the lower part where the filter is acually located. bolted to the body its secured by two 8mm bolts i belive. this is a very common problem with these. it is easier to get it form below but if you pull the air cleaner box out you can get it form the top.
