^ shows whats wrong.

Your car can display the heater level on a scale of 0-16 (0=cold 16=hot)
Your car will display this by hold the power button and the seek up button at the same time.

You can follow the fix above, or, take the temp control **** off and (very ghetto) jam some paper or something else in there to get heat until you feel like fixing it.

 

I just fixed this on my '04 last weekend. Took the circuit board out & soldered. If you're in/around Louisville, and too afraid to do it, come by sometime and we can take care of it.

Dealer will charge a fortune, as the circuit board is +/- $300 plus labor...

 

Want to take a trip up to the Football Hall of Fame? (and while you're here fix mine?)

 

how much would you charge me to do this

 

How's $50 sound?

Hmm.... That's a pretty long drive...

Im gonna see if I can do it then Ill let you know

 

Thanks man I got it hopefully it works now i just have to put it back in the car

 

so i put the head unit back in the dash and hook all the wires up before i screwed it back down and the radio cdplayer and display doesnt work

 

check fuses you may have blew one!!!!

 

had the same problem with my 05 rx8, and the dealer replaced heater control module free under warranty item

 

I checked the fuses and they were all good and then I took it all apart and rechecked all connections and put it back in and it work fine so its all good. thanks everybody for the help
