Automotive connector problem

01/11/2022 4:31 AM

Good day all,

Recently, I detected that my Vauxhall Tigra 2007 1.4 Twintop coolant fan, one of the speeds is not working. After a bit of investigation according to this, I think the culprit is the fan connector socket. It is a 3 pin female jobbie. Type of plug would help.

Anyone have ideas of it? Many thanks.

Why do you think the problem is the connector? Does it looked damaged?

Would contact cleaner help?

Can you take a picture of the connectors with a ruler so we can see exactly what size and type the connector is.

If the connector is burnt, then it's likely the fan is failing....I would go ahead and change the fan out, pretty cheap, before it damages the fuse block...but you need to do a proper troubleshoot and look at all the components, the relays, the fuses...If the fan is drawing too much amperage and you repair just the connection, it could lead to a more expensive fix, and is likely to fail sooner rather than later....If the connector is burnt, you should also check where the wire connects to the back of the fuse block, as that connection may be burnt as well...sometimes they use a 3 wire connection and one circuit is not used, if that is the case you can switch the pins and clean the connector and use the extra wire for that speed...look for a video to repair on youtube....

After a brief search, it turns out that a replacement new fan with socket is available for less than £40GBP including postage. Its fitting, which appears to be a DIY-job, would eliminate all further concerns.

Not a very good troubleshoot here, and not the correct year, so for what it's worth...

...but there's a bunch more you can check out...

Check the plug and socket for corrosion for this happens often in the engine compartment to the conectors. It may be the fan failing but more likely a bad connection on the plug/socket generating heat or oxidisation.

Either change both socket and connector or clean them up well with a small file or sandpaper. Suitable connectors can be found on ebay for a fraction of the cost of a new fan or genuine parts.

Then before reconnecting them apply di-electric grease to the contacts which will protect them from corrosion and waterproof them, can recommend it for slide switches to improve contact and switchability.
