@xstian "Don't use those blue pre-insulated crimps, they have no place in a automotive loom." why? used them for years, with few problems, certainly better than choc block and sellotape that I've found on one old bike. What do you have against them?
It is usually a case of "everyone says so" without any more info! The prejudice comes from the fact that people will use pliers to crimp them and of course they fall off. Same thing when the wrong size is used and so it isn't secure. Fit the correct size crimp to the correct wire with ratchet crimp tool and they will be fine.
The looks are a different matter of course, some classic owners don't like the appearance, which is Fairy Snuff really.

Zafiras had problems with fans, fan itself, wiring loom and thermal fuse were the problems. No idea if your Vauxhall’s shares any common parts with the Zafira. I would be checking it all very closely.
Crimped correctly like you say, and used inside, I too have had no trouble.
Used in areas exposed to moisture, and they will eventually give trouble from corrosion.
Having said that, most of my cars use non-insulated crimped terminals for the earth connections and a fair few engine sensor connections (albeit inserted in plastic carrier plugs/sockets) from the manufacturer. Even then I think I've probably had more hassle from snapping the old and brittle locking catch assemblies of superseal connectors by accident.
"A little knowledge is dangerous" springs to mind.
The Zafira issue was the heater blower resistor, and only if you'd fitted an aftermarket resistor. Certainly nothing to do with the coolant fan.
Excellent company to do business with.
The owner is very knowledgeable about his products, and whenever I've rung him and told him I need something for a job but I'm not sure what I need, he's asked lots of questions and ended up selling me the very thing I needed, even though I didn't know what it was...
Sorry you are wrong, it was nothing to with aftermarket resistors. Vauxhall tried to blame owners by saying this. I was a Zafira owner where everything was Vauxhall original parts and it still tried to go on fire. Vauxhall replaced everything through the recall, genuine parts, recalled again because the fan wiring loom was sub standard.
I think you are the one with little knowledge of the Zafira issues
I could get you a full copy of the recall, but I've forgotten my log-in details for the dealer portal. (I had to change it last week, but need my notepad from work to remind myself!)
There have been lots of problems with heater resistor connectors over the past few years (Vauxhall and Fiat have been the worst for them), which leads to the looms heating up due to poor connections, but they usually eventually fail open circuit, either due to the contacts opening up due to heat, or the thermal fuse within the resistor blowing. I've seen quite a few with wiring insulation discoloured to a few inches away from the resistor due to poor contacts, causing everything to heat up. A good repair is a new resistor and connector/loom, but I've some questionable 'repairs'.
I've even come across one where somebody had bypassed the thermal fuse, as it kept failing. Unsurprisingly, it melted quite a bit of wiring.
Manufacturer's fascinate me at times. Things that have worked perfectly for years, they somehow manage to screw up spectacularly. It's not like specifying a connector capable of ~25A is rocket science, but they somehow manage it.
Thanks but I don’t need a copy. Our Zafira went to two main dealers. We did nothing to the car, no after market parts. Main dealers put all new parts on as supplied by Vauxhall. They all spouted the rubbish line that we, the owners were putting after market bits on.Some may have, I certainly didn’t. I took on Vauxhall through phone calls and emails. Peter whatever his name is, refused to talk with me. His female PA got the job. She realised quickly that I wasn’t going away. They ended up paying all my expenses, fuel, ferry and so on.My argument was none of what was going on was my fault, I bought the car in good faith, the problem was their poor quality parts.
I have a defect on my Vauxhall Tigra 2007 1.4 Twintop coolant fan. One of the speeds is not working. After a bit of investigation I think the culprit is the fan connector socket. It is a 3 pin female jobbie . Type of plug would help.
The big issue with standard insulated crimps, is modern wire will corrode very fast, if salt water gets near it. The record I've personally seen, was somebody pierced a loom with a test lamp on a lorry trying to fix a fault, and it was back less than 4 weeks later with another fault, due to the wiring being completed corroded where it had been pierced.
Modern insulation doesn't seal if damaged, modern wire isn't normally tinned, and modern cable is usually made of more finer strands for flexibility, all of which when combined with salt water, results in lots of white powder with no conductivity, in a very short time frame.
Anything exposed on a modern vehicle, will most likely either be using fully sealed connectors, heatshrink terminals, or will be using tinned wire. Off course, there are some exceptions, like Vivaro/Traffic earth braids, or early Doblo earth cables that had exposed crimps, which regularly fail.
