Hello
I have 2000 regal. For the last 6 months i have been trying to figure out why the HVAC sometimes works & sometimes it doesn't work, i have replaced the control head, check all the electrical connections, At least the ones i can get to.., Here's an example, I'll drive to work,the hvac works fine, I'll leave work and it won't work, ( It doesn't do that all of the time, it might work for days then nothing.) I'll sometimes stop to go shopping after work and it starts working again!!
Any help would be GREAT!!!!
