Electrical Issues with Heater & Headunit
 

Already posted this question in the Heater DIY but no luck in getting much help.

Did the Heater soldering DIY. It fixed the heater control BUT there's still an odd issue:

*When I put the key in the car, go to the A/C TEMP menu and I turn the heater, it successfully goes 0,1,2,3,4,5,6 etc. so the soldering fixed this

*As soon as I turn the key to the "ON" position, the A/C TEMP menu goes back to 0 and stays there regardless if I turn it or not. It keeps blowing cold air.

*Turn the key back to OFF - the A/C TEMP shows the proper number again

*All buttons work (A/C, defrost, radio etc.) but the green lights on the buttons in the middle have disappeared

What could this be? Please help.

Thank you in advance.

anyone?
