We changed the battery in my Trailblazer and now I have no control of the A/C or heater fans nor do I have any digital read out. The fan and temp settings can be controlled at both the dashboard and on the steering wheel. It also is a dual climate control. The fan is running when the vehicle is on however it is only blowing hot air which is about ready to melt me since the temp out side is in the 80s and low 90s. Unfortunately I have already paid an auto shop $75 to tell me they don't know what is wrong.
