I am having a few problems with my Concorde!

Stereo comes on but nothing but static comes out of the speakers

I do not know how to reset the computer that shows mpg & temp

Major one here, AC comes on but only blows hot air no matter what temp I set it to but the dealership says they just topped off the freeon.

 

apply parking brake put car in neutral with car off (this helps with next step)

ok remove center console (wood trim on mine) or the thing around the stereo

unplug the traction control and cigarette light

pull plastic completely away and unscrew headunit (4 screws)

pull headunit out until u can reach antenna wire that is in the back of headunit

unplug antenna then plug it back in to reset headunit

put back together (remember cigarette lighter and TCS plugs)

if this doesnt work then idk...

finally this one. Replace the fuse and get back to me... my mechanic couldnt find the problem he pulled my engine compartment open enough and checked all relays but first he checked the fuse and the fuse was fine. we took it to the dealership they replaced the fuse and it has worked ever since. mine didnt work for 6 months before this was found out.

problem? fans were rewired after a collision and my personal mechanic didnt cover the wires correctly and so the fans short circuited the fuse for the compressor

fix? replace fuse and they said replace the fans but i havent yet and its been a few months and it still works they told me if it ever short circuits again then to replace the fuse and it'll work for 5 minutes or 5 years theres no telling without new fans.

prepared? I have 4 fuses in my car for it.
