Looking for some help with a recent problem with my car:
I was driving up the road the other day in the rain, with the wipers on auto. After about an hour they stopped working. I thought it may have been a problem with the rain sensor, but it was the same at all stick positions. I pulled in off the motorway (hard to see!), and had a poke about the fusebox. Couldn't find any fuses for the front wipers, and couldn't see any damage around the wipers themselves. Tried again after 5 mins and they were working again so I set off back on my way. 15 mins later and they stopped working again.... and so on. Today they weren't working at all initially, even when cold, and then after 15 mins of driving they started working again.... so not necessarily a heat issue.
Anyway, I've had a look around the forums, and it seems like there's two possible explanations: either the relay in the E-box or the motor itself. I figure the relay is easy to change (can you just pull it out?), whereas the motor will be much more difficult. Can anybody advise which is most likely?
When the wipers do actually work then they seem to work well - normal speed, no strange noises, nothing to suggest any mechanical issues whatsoever. And when they don't work they don't respond to anything whatsoever. They never stop mid cycle either, always at the 'idle' position. So I'm fairly sure it's an electrical problem. Could these symptoms be caused by a motor fault, or is it safe to assume a new relay will fix it?
Thanks in advance for your assistance.
