Swift Airconditioning performance

Do you run in exhaust air mode alot? If so cleaning the grill and fan unit inside dash is a good idea, otherwise it's too early. Get grill and interior temperature checked that will give you an idea if that 2k is worth it.

I always run in air recirculation mode. Very rarely uses the fresh air mode. I can't get which one you are mentioning as exhaust air mode?

Are you sure that there is a cut off system in Swift AC. Because the MASS technician said its all on the engine revving. There is no cut off system in swift AC.

There definitely is a cut-off system on the Swift. There is a compressor relay that controls it. When you connect a Tech2 scanner to the car and switch on the A/C you can see the compressor relay changing to 'ON' let it idle for some time and you will see it go to 'OFF' automatically.

i am using my VXI for close to 2 years now and i drive 100% AC always..found the AC to be really effective, hope its some minor fault on your car

Do share the info once you find the rootcause

I understand that A/C steals power, but in my case it is really bad.

I drove a test drive demo also, and it was much better. Something may be wrong with my compressor.

Also, if i have not used AC for lets say...2 weeks, when i turn it on i hear "Pssssssst" sound from the engine bay for first 2 seconds. I feel this is normal though.

anyone experience this?

vikram_d · 2nd January 2009, 12:31

Rohit, I would recommend that you get it checked at an authorised service station.

emkay456 · 2nd January 2009, 12:34

Definitely some drag can be expected but not severe enough to be very noticeable. Even that drag is limited to 1st/2nd gears which are the Achilles heal of the Swift P. I generally power on the AC only if I have reached the 3rd gear and only when caught in traffic jams do I operate it below that.
Yes that squealing sound "Pssst" is there but i think that is more to do with the gas circulation in the A/C and nothing much to worry about.

I managed to find time to take the car to an exclusive Car airconditioner servicing centre at Sanpada. They inspected it and said that gas pipe should be very cold while A/c is running which it not happening and said that gas is not full. It is only about 60% filled. Also he talked about replacing some Vial..(not sure this is mistaken for some mispronounciation). He said gas filling etc and servicing would cost Rs. 1500. I decided to postpone it till March end as otherwise A/c is satisfactory.

Ideally, get your car AC serviced from an authorized centre, you haven't kept any inlet filters near the vents I suppose?.

If that pssst sound is getting high pitched, it might be a good idea to get the tubing checked as well.

Today got SIMRAN to do the A/c mtce. They charged Rs. 2200 + taxes for the same which included gas replacement, cleaning and "compressor oil". Dont know what compress oil change is !! Seemed to be a gimmick. They connected two pipes from a machine for about an hour for the whole exercise.
Now cooling is satisfactory.

Oh, interesting. Does that mean that the Automatic Climate Control in ZXi will switch off the compressor when the desired temperature is reached and then switch it back on when needed?

Compressor oil does not need changing. I was told by my a/c repair specialist that anybody who says you have to change your comp. oil is playing a fast one on you - the only time its changed is when the compressor is opened up for repairs.

Can anyone tell me when the AC cutoff is activated? I tried to observe this in my Swift D and I couldnt find the rpm dropping to 800 rpm from the usual 900 rpm level which is maintained whenever AC is switched on. I then began to suspect some problem with the AC and want to raise this at the MASS during next service. Also the gas in the system was only 310 grams versus the recommended level of 390 grams. Considering that the car is almost 1 year old, is such a drop in refridgerant gas level normal?

There is no AC cut off system in Swift. This I am telling you based on my personal experience. The MASS engineer told me that in swift the cooling gets adjusted based on how fast you are driving. The more you are accelerating, the cooling would be more and faster. He showed me by revving the car in idle. He had connected a temperature monitor to the AC vents. He revved the car upto 2000rpm and the temperature started dropping as against 900rpm. As you reduce the rpm the temperature drop stops and cooling effect starts reducing as you reduce the acceleration and would default to whatever minimum at 900rpm.
