HI,

Ok, does yours have manual or automatic climate controls?

And does it have separate temperature control for the driver and passenger side?

Customer: replied 6 months ago.

Expert:  Eric replied 6 months ago.

HI,

With the ac running, are the metal lines going to the firewall in the engine compartment cold?

Customer: replied 6 months ago.
Customer: replied 6 months ago.
i have a cold line and the compressor just kiced on and it is getting cold
Customer: replied 6 months ago.
with the motor running we switch on the a?c on the dash and it takes a second for the compressor to kick on !!!!!!!!
Expert:  Eric replied 6 months ago.

HI,

Ok, so it is blowing cold out the vents right now, correct?

Customer: replied 6 months ago.
but it now starts getting cold air through the vents !!!!!!!!!!!
Expert:  Eric replied 6 months ago.

HI,

Ok, the AC switch contacts may be worn and didnt make good contact to kick on the ac, or the control unit is not sending consistent signal to the temperature blend doors.

Customer: replied 6 months ago.
eric what can i do to fix this it might even need a recharge?????
Expert:  Eric replied 6 months ago.

HI,

It shouldnt need a recharge as it is blowing cold when it works, which seems to have been consistent until today.

This is going to be an electrical issue, either in the control panel or possibly at the ecm, or in the wiring.

With it working right now, we really cant do any testing as it will show as being good for any tests.

Customer: replied 6 months ago.
it blows cold but it takes awhile and also it takes a little time for the a/c compressor to kick on
Expert:  Eric replied 6 months ago.

HI,

That points to the compressor not getting the signal immediately when ac is selected at the control panel. The signal goes from the control panel to the ecm, and then to the compressor clutch relay and then to the compressor

Customer: replied 6 months ago.
bad contacts on the swich- ecm - compressor- recharge what do you think
Expert:  david craig replied 6 months ago.

Hi Im David, You said you are hearing a ticking noise behind the dash? being that your ac is intermittently blowing cold air and there seems to be a good charge, I believe you are having an issue with the blend door actuator. that ticking means that the arm that controls the blend door is eithe popped off or about to.
