How do I test this relay?
How do I test this relay?
The pins are numbered 1,4,2 across the top and then 5 in the middle and 3 at the bottom. The cover I think is positioned correctly according to the pins of the relay. thank you macafee2 |

Place your multimeter on a low resistance range across pins 3 & 4. You will either get a reading of zero ohms or infinite resistance.
Now place 12v across pins 1 & 2. The reading on the meter should change to the opposite state. In other words, if you got zero ohms to begin with, after application of the 12v you should see infinite resistance. Simon

I have tested the relay that was in the car and a spare and both act the way you describe. I have to say now I have looked at it, I struggle with the relay being stuck but as I don't know and a mechanic says it was stuck, I don't really know what to think. I'll fit the spare relay, use the car at the weekend and go back to the dealer making sure they have UV or what ever to detect the dye. As a main dealer, rightly or wrongly I have blind faith they are true an honest. thank you for the advice macafee2 |

My advice remains the same. For air conditioning, seek a self-employed sole trader or small business which specialises in it. But did you use your air con. much between April and now? Was in it use over the winter? You may well just be looking at refrigerant loss due to lack of use (the seals dry out and allow the high pressure gas to escape). Leave it switched on for a week or two and see if it consistently delivers cold air. If not, then you should have some dye to look for! Quote:

When I had the car re-gassed a few years ago this was indeed the problem, lack of gas. I'll see what the weekend brings. I did not use the air con on the way home today in case the relay was faulty but i live and learn macafee2 |

Brian ** According to the resident armchair expert you should now be rushing around seeking your local independent air conditioning expert, this of course is completely unnecessary |
