It seems your fan, as well as gas needs to be checked.
My advice would be to go to any AC guy outside hyundai.It will be cheaper, and if he cant fix it, you can go to Hyundai.

And yeah, these things do let go this suddenly.

switched to outside air may be after 1 month or so. I feel gas and compressor is fine because lot of water is coming out of AC drain which indicates compressor is working fine. Fan speed also looks fine.

Default Re: What to check for outside smell entering the car cabin?

On our recent trip to Goa, I was driving a BMW 3 series. Although the insulation is really well taken care of, I noticed a tiny stream of air flowing through the door lever on the inside. It was noticable only during high speeds (90kmph & above).

checked with Hyundai service station, as per them the motor which get operated with recirculation button has gone bad. this motor is placed next to air filter behind glove box. The effort needed to replace this motor is to remove entire dashboard which i am reluctant to do as this will create lot rattles in future.
I am just wondering if a motor can rotate some sort of switch or flap which toggles between fresh air, how about rotating it manually and then let it be like that, this will not enable recirculation but it could be a quick fix to avoid sucking outside air.

The reason for motor not operating could be lose connections.

please suggest

While manual "jamming" might be a temporary solution , it may cause other much more serious issues . Many modern ACs in recirculation mode are programmed to go back to ventilation mode fpor a short period after a certain duration , thats because after a while the air inside the car becomes stale ( i.e. less oxygen) which increases driving fatigue and in extreme cases may cause extreme drowsiness thus creating unsafe driving conditions .
I think trusting the workshop and getting the fix is an advisable solution.

Default Re: What to check for outside smell entering the car cabin?

I thought of looking at the problem on my own of outside smell and service station told me the motor for air vent has gone bad. I opened the glove box and reached the area where all these controls are placed. I was shocked to see that AC Air filter was missing, this looks like a deliberate mischief by service station as there is no need to remove the filter. This could have been done to get more business in future as removing ac air filter will create problems with HVAC system and in long run probably complete breakdown of HVAC system. First sign is already visible : failure of recirculation motor because lot of dust and dirt could enter the system.

Could anyone confirm if AC filter is present in Verna or not ? Mine is First model of Verna. Please suggest future course of action.

after researching a bit i have learnt that auto climate control ACs are designed to pull in certain amount of fresh air despite of recirculation mode to avoid humidity and stale air.
One approach is to use a cabin air filter containing activated carbon. Normal air filters can keep particles like dust and pollen at bay. Activated carbon takes things a step further by absorbing smoke and its constituent harmful gasses. It absorbs odor too.
Hope this helps.

I agree and I have read your DIY.

Can you tell me what is the life of the filter versus the standard one?

Bosch recommends changing the filter after 1 year or 15K Km whichever is earlier.
