Subject: RE:C4 radio and heat/ac not working by VtVette on 2007/9/3 5:37:29 In the engine compartment on the right hand (passengers) side in front of the heater box on the top of the frame rail you should see a ground wire screwed to the frame. Check this ground it's for the blower motor among other things but can cause all kinds of issues if it's bad. Also check the ground in front of the passengers side door below the "A" pillar. That is where the radio head unit is ultimately grounded. The HVAC head unit grounds at the drivers side lower "A" pillar ground in front of the drivers side door. The heater/AC programmer ground could also be causing issues. This unit grounds at the same place as the HVAC head unit mentioned above. |
