Fans and blowing fuses

Post by ttedj »

One of the rad fans lost it's magnet so I replaced it. Runs fine but keeps on blowing fuses after a while. Spins freely etc. Any ideas as to why this would be and also why when the l/h fuse blows do both fans stop?

Thanks

It seems that both fans are fused through 1 fuse. Removing the r/h fan fuse does nothing and both fans work fine. Remove the l/h fuse and they both fail with fail light on. Will have to track down someone's bogging somewhere. On a good note passed the mot.

Seems that someone cut the wire to the left fan and wired it to the right supply. Why you would do this I do not know. Maybe they had fitted the wrong type of relay and could only get 1 fan to work. All fixed now though.

That's a problem with older cars, you get so many changes made by previous owners that you don't know the details of.
