When you replaced the battery, did you remove the negative cable first, and attach it last? Try that first, then this is the test for the left side air temp not changing:
LEFT OUTLET TEMPERATURE DOES NOT CHANGE 1. Check for faulty HVAC (10-amp) fuse in instrument panel fuse block. If fuse is okay, go to next step. If fuse is open, go to step 3. 2. Check for a short to ground in Brown wire between instrument panel fuse block and A/C- heater control unit. Go to step 8. 3. Disconnect left-side temperature valve actuator connector. Turn ignition switch to RUN position. Using a DVOM, measure voltage between left-side temperature valve actuator harness connector terminal No. 5 (Brown wire) and ground. If voltage is 9-14 volts, go to step 5. If voltage is not 9-14 volts, go to next step. 4. Check for poor connection or open in Brown wire between left-side temperature valve actuator and HVAC (10-amp) fuse. Go to step 8. 5. Using a DVOM, measure voltage between left-side temperature valve actuator harness connector terminal No. 6 (Blue wire) and ground. Switch driver' temperature from full cold to full hot. Voltage should vary between.5 and 4.5 volts. If voltage varies as specified, replace left-side temperature valve actuator. If voltage does not vary as specified, go to next step. 6. Check for a short to ground or battery voltage in Dark Blue wire between left-side temperature valve actuator connector terminal No. 6 and A/C-heater control unit connector terminal C7. If wire is okay, go to next step. 7. Check for a poor connection or an open in Dark Blue wire between left-side temperature valve actuator connector and A/C-heater control unit. If wire is okay, go to next step. If wire is not okay, replace A/C-heater control unit. Go to next step. 8. Install a scan tool with appropriate cartridge and check for any DTCs that may be set. If any DTCs are set, go to appropriate DTC test. Page 1 of 1 4/29/2010 .
