Cooling can be fine just open the bonnet and see if a rat got inside somehow.

Apart from a dead animal, even melting plastic wires due to sparking etc. causes similar odours.

Hi all,

Having a peculiar issue with my Terrano’s AC. Situation is as below:
1. Take out the vehicle from shade -> AC working fine.
2. Park it in front of the under hot sun( kerala climate) for 30 mins
3. Start vehicle -> no cooling only blows hot air. (Travelled distance of 10 kms)
4. Stop vehicle and run some errands
5. Start vehicle -> cooling back to normal whole way back 10kms

Situation 1 to 5 has happened twice.

Evenings when i take it out, cooling seems fine.

Took it to a FNG, AC gas is fine. They say need to check compressor.

Any idea what could be going wrong.

Hello BHPians. I come across a video that claims easy cleaning of car A/C condenser coils. I suspect the liquid used in the video is acidic in nature. Is it safe to use this liquid on condenser?

There exist both acidic and alkaline cleaners, often mixed with a detergent for foaming, but these are about the strength level of harpic at the most.

You can even use Vinegar if you like, or liquid soap plus baking soda.

From which location of dash air is sucked in when A/C is in recirculation mode?

Pl. ref following image. What is this red circled port? He suspect it as air input port in A/C recirculation mode but when he checked with piece of paper air is not sucked in/out from this port.

On most if not all cars the air intake will be under the passenger side dashboard, under the glove compartment which is also where you would find the blower motor and possibly the cabin air filter.

The vent you have marked is the defogger vent for the side glasses. The air comes out of there only when the AC is turned to defogger/windshield setting. Then too the air flow from those vents in most cars is a bit slow even in the correct mode

we checked under the passenger side dash. There is no port for the air intake. There is one port under the dash but that blows cold air to the foot when that mode is selected in A/C air control.

It is strange that most of the car A/C takes air from the location bellow the dash. Because for proper convection cycle, A/C must take air from top of the dash.

In most cases there won't be a visible intake vent under the dash but it's the location in 99% of the cars. If you see the blower motor you can try and trace the path if you want or if it comes out easily then remove the glove compartment to check.
Did you also check if the upper vents throw air in defogger mode ?

Yes upper vents throw air in defogger mode. It is good idea to trace path by removing glove compartment.

I think I broke something on the Alto K10 AC direction setting contraption. It seemed like something was stuck and I turned the knob a bit too hard. Now the air comes out only in one position (face) and I am unable to shift it to other positions even though the knob seems to be turning - either some gear has jumped out of place or is broken - any way to fix this without changing the whole unit? How do I get to this unit, any hints welcome.

The cable that connects the controls might have slipped out of the clip, do check if that is the case. If so it is a very easy fix. On the other hand if the plastic bits are broken, then you will have to look at replacement, you can try using some heavy gums like Araldite but it would be painful fix and still chances of it giving away.

I've run into a peculiar problem with the air-conditioning in my Ford Ecosport. After the car is stationary for a few hours (engine turned off), the AC refuses to start after the engine is turned on. Once I drive the car for some time (30mins-hour), the AC starts cooling.

Through the entire duration, my blowers work, I am able to change fan speed etc but there isn't any cool air being circulated. I have the car serviced at Motofyx and they advised that I have the 'AC blower resistor' changed which I did, but the problem continues. They are now advising that I change the control value . Frankly, I think they're clueless about what the problem is so I've asked them to return the vehicle.

Any advise on what could be potential issues and any recommendations for trusted AC mechanics in Mumbai?

This sounds like it could be a clogged condenser issue or non working radiator cooling fan issue. Gomes AC opposite Reliance mall near Milan Subway has been reliable for me so far. If the location is convenient to you then you can give him a shot.

I assume that the folks at Motofyx would have cleaned the condenser but nonetheless I’ll have it looked at the garage you mentioned. Thanks a ton!
