You sir solved my issue, I knew there was a separate fuse box but I could not find it. I thought it was a wiper relay or switch on the steering wheel, as I already disassembled wiper motor and it worked with no issue when direct power was applied. Luckily it was just a faulty fuse... you have one like from me.
The motor is not PWM. You have separate windings in the motor for the different speeds. When you saw a steady 12v input that winding/speed was being used. When you saw different erratic voltages another winding was being used, and the one you were measuring induces voltage from the magnets into it's winding becoming a generator. Same happens if you spin any brushed permanent magnet DC motor. Rob.
Robrob iwas going with his signal on his scope the 12v looked like it was being pulled to ground with around 60% duty cycle which would give about 7 v to the motor for slower speed
250 quid the sealey box Sandy , now listed as TA111 ? , great video ,Steve was showing something very similar yesterday from top don on Simply Diagnostics , wires probably stiff coz it's so bleedin cold love 😉😉🤣
please what fuse did you replace. i am having the same similar issue. i have changed the motor and the control stick in steering and i am still having the same issue. can you please elaborate on what fuse was replace. thanks

Perfect! Had this same issue on my lad's Clio. Solved, thank you.

Cheers Rob thanks for information, Sandy

Haha cheers Mike forgot it was Baltic !!!! Sandy

Car showinh stop light with battery light not picking self what we do
Normally the drain gets blocked and the motor gets submerged and eventually gives up did a few worst one shorted out and burnt the fuse box
Cheers my friend for information, it's good to have a fellow Falkirk Bairn on board👍
Hi Mr Anderson ;
I want to ask you what’s the best car diag tool please;
Lot of shiny tech to just change the fuse.
Yep motor speed signal is PWM ......................Which Launch is it Sandy ?
X431 V+ 10 inch
Looks like your motor speed control is by pwm signal mate
Cheers my friend, Sandy
Launch better than Autel ?????? .................my Autel blew up 1 week after warranty expired and they wouldn't honour it under goodwill.
Autel better than Launch!
