I have an 02 ls. I recently changed the radiador and bled the cooling system. Today I turned on the heat ater the temp gauge reached the half-way mark and noticed I did have any. I touched the three lines going to the heater core and only the bottom line is too hot too touch. The two top lines are only luke warm. I touched the hose going to the DCCV and it was hot. I noticed the ac compressor clicks on and off about every 30 seconds or so.
I also ran a self-diagnosis text on the climate control (key on, hold off and floor buttons then touch auto button) and got all eights. so What can the problem be?
