Air Con not working

[Shahid1973]

Hi Everyone
I have 2011 Honda Jazz and typically with weather being scorching the Aircon was not blowing cold air.so yesterday I got it regassed yet the cool air blows for a few minutes then the air is warm.Can anyone please help me as to what I need to do to get the issue resolved so I can use the Jazz especially during the hot weather.

I would take it back to where you got the regas. Maybe they didn't do up the inlet schrader valve? If not, ask them to diagnose. Worth a google for AC specialists in your area if further help needed.

Hi I'm not an expert but it could be a worn/stuck relay.
Just had regas yday , no joy , warm
air , actually got a refund cos it didn't work , who knew 🤷
Guy said could be pump or sensor , so as you do I headed to Google and YouTube.
By chance I stumbled across a post about tapping the relay with a screwdriver driver.
Sure enough I tried it and the clutch kicked in and I briefly had cold air.
However as I've now learned the ac cycles on and off , and after first cycle it wouldn't re-engage , UNTIL , another tap. My takeaway is that it's the relay so I've ordered a new one and hopefully that cures it , fingers crossed.
Will report back later.
Location of the small relay box in my car ( 2010 EX ) is next to window washer top up , very accessible.
To remove the relay I had to grab , very gently , with some grips.
The box lid itself just has two squeeze? clips , very easy .
All I will say is be VERY careful if tapping relay with engine running, I nearly dropped screwdriver and it's right where all the belts are spinning rather fast :-)

Just to add , inside the relay box there are 3 relays , two are parallel, the third is at 90⁰ to those , sits atop them basically.
In my car it's the third that is the ac clutch relay.

Can confirm the new relay did the trick.
So my situation was as follows.
1. Warm air
2. Condenser fan was working .
3. Clutch was free and spinning when not engaged with engine off
4. The system was cycling on/off as should do but clutch did not engage.
5. Clutch would engage with tap on the relay with screwdriver handle.
6. Clutch didn't re engage after first cycle
7. Replaced relay ( £9 ish ) , issue resolved and now have working Aircon.

Hope this helps someone.

I did hope that that was my thing too so went and replaced the relay but don't know for how long AC needs be on before it kicks in? Yes, it has been regassed last year. And the other thing, the location previous shown here? There is no relay box there  but at the right of the starter battery(!) Pic is after I removed the battery. My one is a 2011 -GG (mid trim).

Ah ok , forgot to add my model.

2010 EX , no idea why relay box is in different places. That said a US vid I watched had the relay box just to right of battery, first place I looked.
But then found it by washer.

Is your clutch spinning freely when the engine is off?
