I can see the refrigerant gas boil through the glass window under the hood, and I also had it checked with Cool World, Nagpur, who confirmed that the refrigerant is full. I also had the cooling coils cleaned at 35,000 kms and the whole blower, ducts, radiator coils, etc are generally dust free.
I am now begining to suspect that my AC compressor has become weak and therefore the cooling is reduced. How do I confirm this? Can the compressor be re-conditioned? Are there any seals that need to be replaced over time? Will reducing the refrigerant pressure help? The compressor runs continously and does not cut-off, as the grill temperature does not drop significantly. I need to fix the AC soon as it has become impossible to drive the car in the afternoons! And with the monsoon nowhere in sight, it looks like another fortnight of opressive heat.
Any pointers, suggestions, solutions, welcome |
I have a Zen LXi so fully understand how frustrating the a/c can be..
With a temp. like 45 deg, it will anyway be difficult for an a/c and that too a low-powered one that Zen has to cool the cabin fast or to maintain it at a pleasant temp.
Zen by itself has a weak a/c and changing the a/c compressor itself isn't a very advisable solution; so this is something you can't help..
What you can do is have a fairly dark (and yet RTO approved) sun film for the windows.
You can try this : the moment you sit in the car, open all the windows and drive this way for a short while (100-200m) to let the warm air out.. then roll the glass up and start the a/c. I've tried this in Gurgaon (similar ~45 deg temp) and it helps..
Of course, keep the refrigerant (a/c gas) level at optimum level. |
