That is a pretty "sticky" subject, hopefully this will work.
You will need to buy a can of Aerosol Computer & Electronics Cleaner:
"A+ Electrical Contact Cleaner #16136" from RTX Scientific Inc.
>>>High grade solvent for cleaning a wide range of electrical components. Compatible with most plastics and PC boards. A fast drying fluid that does not leave behind any residue. Does not contain petroleum distillates, nPB, alcohol, acetone, glycol ethers or chlorinated compounds. Extremely low odor<<<.
A+ is very good Electrical Contact Cleaner #16136 but it is a little expensive ($29.95) available at this link:

I would ask around some electronics repair shops and try to find out what they would recommend too and decide which you would purchase.
I "strongly" feel this procedure is going to work but, I can not guarantee it "Electronics are very sensitive"
and when water/fluid it introduced to them !!...you know the rest of the story from there.
(The stereo and the heater constantly change and move up and down on their own)
>>Actually that is a "good sign" because it shows they are still receiving power and not short circuited<<.
Personally I would buy the A+ like they say, "You get what you pay for" again it is ($29.95). It's up to you.
>>You are going to attempt to clean the circuit contacts under the buttons inside the steering wheel<<. Once you decide what electrical contact cleaner you want your ready to start.
Here we go, I hope this does it for you.
With the contact cleaner you need these items:
* Get a thin blade pointed knife or "small" thin blade screw driver.
* Get a blow dryer (If you have electricity nearby) if not let it pass.
* Get a small amount of soft absorbent paper towels or tissue.
* Get some "Q" tips or similar - (about a dozen or so)
* Small amount of Super glue or similar.
>> All the switch identifiers are just "covers" to a rocker switch underneath. With the thin bladed knife or very small screw driver ...Only "one" at a time gently pry up the identifier cover: example "TEMP". Pry gently and slowly from side to side, top and bottom ...it "will" come out "guaranteed". When it starts to come out go very, very slow with the removal. There is a circuit board underneath with small contacts etc. that make the circuit work.
Keep a strong lookout making sure that any of the (2) very small "pink" 1/8" round rubber contact cushions attached to the bottom of the identifier cover do not fall off. The pink contact cushions sit on very small black plastic holding/positioning "pins"
Place the cover identifier with the pink contact cushions attached on a stable surface. "STOP" take a break.. the hard part is over, you are ready to clean that specific switch circuit contacts and board (Next). Remember only "one" button cover identifier at a time, go slow...take your time.
***Disconnect the negative cable from your battery***
*** (("HELPFUL TIP"))>>> Apply a very small amount of super glue or similar to permanently hold the "pink"contact cushions onto the holding/positioning "pins" This will make it much easier when you re-install the identifier cover!<<<***
If you have a blow dryer put it on low heat, high air flow and hold it close to the opening slowly pulling it away after 10 seconds for about 20 seconds, you do not want to "Burn" the circuit with high heat. (Your trying to push/move any moisture that may be in there). If you do not have blow dryer capabilities, that's O.K. (No Problem).
With a small amount of paper towel or tissue gently push the paper into the opening onto the circuit board. (You are trying to remove any moisture that may be in there).
Once you are sure it is completely dry, spray a small amount of contact cleaner inside the opening, let it dry for a minute. Repeat the spray procedure (3 times total).
Spray in some contact cleaner and "Gently" rub all the contact surfaces, contacts etc. with a "Q" tip or similar. Do this procedure (3 times total) use a new "Q" tip each time (Do Not Re-use the "Q" tip) it is soiled and that is what you want, to remove any soil that may be in there. Re-using the "Q" tip will just put it back.
Now everything should be nice and dry and clean.
With the pink contact cushions securely glued to the plastic holding/positioning "pins" you no longer need to be cautious of having them fall out. Gently guide the cover back in place. The are two very small holes on the side that slip into a very small "Pin type" hinge. Try it out and I hope it works for you. Do the same procedure to all the button switches.
Let me know how you made out. Any questions just private message me and I will get right back to you.
Good Luck;
Rick
