AC Controls failed when Mother in law got in
OK Here is what I have going on. When I start the car 430 CLK the blower indicator was blowing 50% I tried to increase it by pushing the appropriate buttons and it would not increase I then tried to lower :-( and it lowed it, bad idea. I could not get it back to go up. Turn off and restarted several times, pushing buttons. Now I think I have a CODE issue. This is what works
1. My Defroster, light comes on and blows high, don't need it when it is 99 degrees.
2. Rear defroster light will come on.
3. No other lights
What won't work
1. No light on AC control - non responsive
2. No temperature reading
3. NO EC light indicator
4. No Recirculating indicator
TWO Options
1 Defrost mode or two OFF indicators.
2. Check # 25 fuse OK for blower motor which figures since defroster blower works. Yet is there another fuse I can't find?
3. Tried to reset codes and all I get is a "1" displayed on the left side and another three digit number on the right side. I think it is a temperature reading since it read 131 and changed as the blower was working.
Tried this several times Could not get to an error code. Turning the key to the second position and pushing the EC and REST button at the same time?
Any help would be appreciated since it will be 100 + here in a few days.
Thanks

Hello and welcome to the forum! What scan tool were you using to read and reset the error codes? What were the actual codes that came up? Code P0131 is for the O2 sensor.

The last two hours I was running a Carsoft MB I I diagnostic tool, auto and manual diagnostics on all systems and just AC but didn't result in anything.
Now for some reason while hooked up my gauges started to jump and make static sounds over my turned off radio. Pulled the plug. Car won't start now. Have no idea what caused that?
Tried diagnostic again no errors but something is amiss ...Like a cooked control module for one.
back to square one
