Ac Not Working Properly In Toyota Corolla Nze121 G Grade 2004

Recommended Posts

I'm having a Toyota Corolla NZE121 G Grade 2004 (This model has reverse lights in the dickey) and when I start the car and press the AC button on the AC starts but blows normal hot air. Then after 2-5 mins cold air starts to come out. Once the cold air starts to come out the AC continues working fine without failing again. The only issue is that there is a delay of few minutes for the cold air to blow. I've checked the fuse box and this model doesn't have a MG-CLT relay installed. And when I check the AC compressor I can't see the magnatic clutch from out side.

I checked with the AC technician and he said this model doesn't have magnatic clutch and has a belt type unit. And also he said there might be issues with control valves. He said the solution is to replace the compressor with a unit with a magnatic clutch.

Does anyone have an idea about this problem and how it can be fixed.

Aiyo malli!

Do you want to go through ALL that trouble and spend 20-30k, maybe even more on a new compressor (which is more than the money you save on petrol because you bought a 'corolla') or suck it up and bear it for 2-5 mins till the cool air comes?

Whatever you do DONT replace the compressor with a unit with a magnetic clutch (as in a model not intended for your model of car). Ignore all your AC technician tells, better yet find another one who actually knows what he is talking about.

When you are changing compressors unless it is impossible it should be like for like or you will notice other issues like loss of pulling power, loss of fuel economy, AC cutting out too quickly etc etc.

I'm going to do a full AC Service and see if that will sort out this issue.
