aircon prob

I wanted to test if my aircon works. I think it needs regassing anyway, but after a half hour drive with engine temp Upto normal I pulled over and switched aircon button on. The fans didn't fire up. Is my aircon not working.
Also, I was checking fuses under bonnet (with ignition on) and pulled out what I think was fuse 4. The fans then fired up.
Then, I disconnected battery for an hour, reconnected. Switched on aircon but the little light on the aircon switch now doesn't come on. What's going on.

Majority of times you just need a regas, for £50 this is probably your best option. Rule out the cheapest option first before delving deeper or you may be wasting your time and money. Most aircon systems (in my experience) need a regas after about five years, if you get longer then you are lucky.

Kwik fit offer a regas service and if the system doesnt get cooler after, you don't pay

Regas won't help if the fans are not working.:doh:

True but I was following on from the previous post where a regas was suggested
If the system detects lack of pressure and prevents the compressor for cutting in perhaps the fan doesn't run either

Air-con regas is now more expensive than it was like a year ago.

You cant legally regas an aircon system without first carrying out a nitrogen test.

Vac tests no longer count sadly.

So if there's no pressure because it needs regassing then the fans wouldn't come on anyway?

yes you can. Show me where on the F-gas regs it says you cant.

if there is no pressure, then the compressor will not cut in and the fans will not need to come on - trimary switch. easy to tell, put yo hand on the compressor - yu will feel (and hear) it click in.

Cool thanks for all your replies. I supose ill just get the regassing done and go from there
