Hello guys, need your help .

I drive and petrol hyundai accent with 80k on ODO, i got ac serviced couple of months ago. The AC works perfect while cruising, even on stand still it works equally well, BUT while i am in Bumper to Bumper traffic, with clutch depressed it cuts off, like if someone turned the ac off, and start working again when i remove my foot from clutch.

It only happens in crawling traffic, i checked my clutch too, it's fine till date.

What could be the issue, with summers on the peak, it gets difficult to sit in the car with AC off.

I will consult A.S.S over the weekend, anyone experienced this before ?

Please help.

In summers, the temperature of the Engine Oil rises rapidly in start stop traffic. So the AC compressor cuts off temporarily to reduce load on the engine. Once you are back to speed, the air flow to the radiator fan increases this reducing the temperature and the AC compressor switches on.

I dont think this has anything to do with the clutch. Just to be sure just idle your car for 10 min or so with the clutch depressed and check whether the compressor is working. Let us know the feedback.

Just to isolate the clutch thing, is ac working at stand still on neutral (you dont need to press clutch pedal in this case).

Yes, ac is working perfectly fine on neutral .

[nozzlering]

Its strange!! Ac being controlled by Clutch
Any repair job done recently?
I would suggest you to do one small test. Or maybe you have done already. Car is in neutral. Start the car. switch on ac and blower. Cooling will start. Now just press clutch pedal and keep in this position for some time. Is ac working or not?

Ok, you shall laugh. But here's a pointer. Now I have driven 2 Accents over 3 years and I can assuredly tell you nothing is wrong with the car. Do one thing, take a torch and check to the left of the footrest. There is a plastic slit/window that can move with your foot. Every time you put your foot down to depress the clutch or rest your foot on the rest, you might just be opening that slat with your foot. This slat, when open (or closed, I dunno) allows the cool AC air to pass into the centre console.
It's a silly thing, but I have had instances where I have had HOT air coming from the louvres and I don't even know why. I zeroed it down to my foot movements and closed the slat with my foot. Chilled air within seconds.

THIS is an isolated situation and happened to me. Don't consider this as the solution to your problem.

Did the check, in neutral with clutch depressed - AC is still cooling, putted it in the 1st gear, started leaving clutch with accelerator, AC stopped cooling, and little more accelerator, AC again started cooling, don't know what's with it

Will be taking it to the expert tomorrow .

Thanks alot for sharing this, will surely try it tomorrow

I got the reason behind, the problem is that, whenever i release clutch with accelerator along in 1st gear, the rpm goes up and as soon as i start leaving the clutch, rpm drops down for a moment and again rises.

So, when rpm drops AC stops for few seconds and again it starts. Once i go above 1st gear, the problem disappears, that's why it becomes a little irritating in bumper to bumper traffic, where i hardly manage to go above 1st gear.

No, what could be the issue, why rpm drops for a moment, while accelerating in 1st gear ?

i dont think RPM dropping is related to 1st gear.
Try pulling the car in 2nd gear from standstill and check if that happens.

Throttle cable might be getting Jammed at times, do get that checked.

Try this in reverse gear as well to see if it happens.

[1self]

sameerg001, your idle air controller (IAC) is chocked, or on it's way out. That is the reason the rpm drops & then rises again. Get your full intake system decarbed. If the problem persists, then it's the IAC valve.

[sameerg001]

I got the issue, it was related with accelerator cable. Thanks everyone for helping me out on the issue

Good to know that the issue is sorted now.

No need to close the thread, this thread will help people who might face similar issues in future.

Hey guys, i need help with my car AC too. I have the hyundai accent

My car AC used to work perfectly but suddenly it stopped cooling. I went to the AC workshop, there was no leak whatsoever. He advised me to do the servicing of my AC. But its still the same. There is no cooling.

The problem started when my friend was driving the car in a hot afternoon when i had a problem with the bottom of my radiator leaking a little bit of water. There was a noise "gas release type noise(ssshhhhhhh)" from the hood and after that the AC stopped working. I got the radiator's bottom fixed though. Also, there is no coolant.. Just water

First and foremost thing to do - refill the whole loop with the correct ratio of coolant:water at an FNG then check for any leakages etc.

Thanks for the reply Anurag.
But after i'd replaced the bottom of the radiator, the mechanic asked me to not put coolant for 2-3 days because if there was any leak, the coolant would get wasted. He advised me to use the car on water and check the coolant reservoir if it is becomes empty again then there would possibly be more leakage.
