Air condition

[Romeo Borg]

Hi, My problem is on my Toyota corolla 2004 that when I turn on to my air-condition on heat the clutch Motor goes on and off, what is the problem?

Thank you

Hi,

Do you mean the compressor continually cuts in and out? If so that's normal, it's how the system regulates itself.

Hi,

Yes, it cuts in and out but every 20 second, and not heat.

Thank you.

The compressor cutting in and out like that is completely normal.

It's normal. The compressor has to stop at some point to prevent the system from over-pressurising.

Not getting any heat is a separate issue. Car A/C does not provide heat, it provides cooling and drying. But it can be useful to run it together with the heater to dry the air and help with demisting the windows.

Hmm, I vaguely remember the T-Sports sometimes having problems with the heater matrix getting an air-lock or corroding; Assuming the normal Corolla uses the same system, might be worth checking. Have you looked at the coolant?
