Air Con

[graemer]

Had system re-gassed - was working, now not! Should have left alone or is this a coincidence?

 

Compressor clutch is not working. I have checked the connector and find there is power to the clutch; however the power is on all the time! Even with the ignition off there is +10v at the clutch. There must be a fault up the line as I would only expect power when the ignition is on??

I am wondering if this is why my clutch is knackered i.e. being engaged most of the time - what can cause this - could it be the air con relay?

I need to test it but cannot see how to get to it - understand it is on the central junction box but cannot see how to get to it - can anyone tell me how you do? Has anyone out there had the same problem where there is constant power to the compressor clutch?

 

Thanks.

have a look

seems poster had clutch on all the time - some possible diagnostics

 

and his solution was to replace pressure switch

 

faulty pressure switch

Wow - thanks for a prompt response; will have a look at the week end, pressure switch does look like a likely candidate. A complete sod if this little device has cost me my compressor.

Do you know how I can access the central junction box to check the relay as well?

 

PS Added my car details in signature as suggested - thanks.

I think the Central Junction Box is located above the fuses under the drivers dash. To get to the relays you have to remove a couple of screws and swing down the top level on a hinge.

Thanks for the information - will have a look at the w/e.

 

Once I have sorted the electrical side can get a new compressor fitted :unsure: . Have been quoted 280 + VAT for a new one; does anyone know of a cheaper source? I have heard of reconditioned for 240+VAT but this is the cheapest I have seen.

Thanks - had a look but my compressor is model 1226, this one is 1162! Why do they all have to be different - don't answer that!! I'll check them out to see if they can get my model or this one will fit as a 2 year guarantee is very good.

I can also vouch for these guys, I had near on a complete new aircon system fitted about 3 years ago now.

 

Still going strong (why oh why did I just put that)

 

Expensive I think but did an excellent job.

 

I think I ended up spending that much money there the bloke genuinely felt soory for me by the end of it and actually done some little bits for free.

Thanks Guys - you have saved me close to a ton already with these links - fantastic!

Either my local guy can match it or I'll buy the compressor from one of these sites and he can fit it.

Cheers :blink:

I have contacted Coolcar who were the cheapest on the web but the actual price quoted incl VAT and delivery is

My model is slightly different to the one advertised :(.

 

HELP!! Have checked the high pressure switch and this is not the cause of the supply to the clutch remaining on even when ignition turned off. Have pulled all the connectors out of the main junction box on the driver's side and still power! Does anyone have an idea where this baby is getting its power from - the wiring diagrams on the TIS point to a main relay on the central juntion box - from what I can see this powers the clutch so is likely to be the cuplrit but cannot understand why when I disconnect the connectors from the junction box power is stil there. I must be missing something??
