climte controls not working after removing the pannel to install an aftermark radio

[Keith]

after installing an aftermarket radio in my H3 I hooked the heater controls back up to the pannel and when i turned my truck back on I am only recieveing heat in my truck and can not turn on the AC or even change the setting from hot to cold, even with the control on cold it is bloeing out hot air, like the knobs are not registering, the only control I have is the fan 0-4, When I try to change the direction path of the heat from the top to the bottom or the defroster, that doesn't work either, The only thing I can think of that could cause this problem is that when I unhooked the heater controls my shifter was in D so I could access the pannel easier and It seems like the settings saved from when I unhooked the heater controls(heat was on with just the top vents selected "thats all I have now") I guess the only good thing I got out of this was the radio works..... Please help????
