Volvo Troubleshooting Questions? Ask a Mechanic for Answers ASAP
Hi, I'm Ron and I will be helping you today.Stand by for a moment while I prepare your answer.
Okay, so if the switch is good, the motor and wiper module are all that's left.
You can check this with a scan tool in bidirectional mode to confirm which is bad.
After looking again, they changed this and you don't have a module that is separate for the wiper motor any more, you just have a relay in your relay box under the hood. I don't think it controls speeds though, just functionality which would mean that the wiper motor is what's bad.
thanks again and please remember to rate me 5 stars and keep this link in case you need me again later on.
There is not for that problem, make sure that the wiring is good at the connectors, especially the grounds.
They only supply troubleshooting data when a code exists in the computer.
You would still be best off to check it with a scan tool like I said before, because you can also have a problem with the BUS line. The scan tool will tell you everything.
I apologize for having to give you that news, and I sure hope it doesn't affect my rating. I'm just the messenger:)
I'm not sure if this will help you, but I sent you this wiring diagram anyway.
The scan tool really is the best and easiest way to find the problem though. let me know if you need anything else:)
thanks again, Ron
