friends,

I need your earliest help for the AC problem in my Linea. It is a Linea T-Jet Emotion (2014 Model Face-Lift-India).

For last about 6-7 months, the issue of AC is giving troubles. In the begining, some times working and some times not working... stopping during running.. again starting.... and so on..

Meanwhile the above period, I came to know that same thing was happening with the blower fan. It was due to the Resistor, and I recently replaced the same with a new one original. So the blower fan started but the AC is not working.

As of now the AC is totally stopped working.... not working at all.

I have checked fuses and relays... all are ok. Also checked and refilled and updated the refrigerant couple of time but no change in AC behavior.

I studied many posts like:

https://www.fiatforum.com/grande-punto/458206-eleganza-heater-not-blowing.html

https://www.fiatforum.com/grande-pu...ater-fan-wiring-loom.html?344602=#post3425921

etc. and googled many pages, but unable to resolve the issue.

Can any one help me how can I resolve the issue? What may be the causes for this non-working of AC? If any further information is required, I shell be pleased to provide it.

Awaiting your valuable response.

Have it diagnosed with Fiat specific diagnostic equipment which can connect to AC ECU.

I visited FASS, however obd scan didn't result in any relavent error. I am not sure they have checked all parameters and whether their scanner worth capable of connecting to AC ECU.
I am thinking of purchasing an OBD scanner. Can you please suggest a reliable one for Linea Tjet 1.4 (2014)

Generic obd scanners aren't able to connect to canbus. Multiecuscan software with recommended connectors can do it.

Surely AC is not a DIY job, so any ac service center can fix it. It may have leaks and pressure switch prevents the compressor from starting in an order to prevent damage.
