symptom: Pedal goes to floor with car off and with car on. OK here is an update: The Master cylinder is good - tested The brake booster is good - tested bleeder screws/calipers eliminated as a potential problem Brake lines are solid - no corrosion Flex lines seem good - I say this because I was able...

follow up - New fan arrived, installed and I once again have air flow - significantly better than before I might add. High five to the Volvo engineer who placed the fan where it was and made it so easy to swap out. I have done fan replacements which took an entire day because you have to practically...

You are correct - I removed the mounting cover. The motor housing has a decent amount of dust as a result of brush wear.

OK guys - the blower motor failed the bench test - but here's a big FYI I initially hooked it up backwards - reverse of how its connected inside the vehicle. Put 12V to it and it ran flawlessly in half a dozen starts and stops including 3+ minutes with no indication of issue. Then I reversed the lea...

awesome - so can the fan be bench tested once removed? i.e. can I connect my 12vdc power supply to it to test the motor?

At lunch today I went out and tried it and here is what I have: When moving the slide switch from 0 to full blast, the fan initially comes on and blows lik...

Interesting.... so would a valid test be: disconnect the flex line from the hard line and see if I get flow at the hardline/flex line point? assuming the flex line is the issue, i would assume that I would get a good flow of brake fluid at that point if the flex line is the issue. Although possible,...

follow on to that - looks like I am upgrading my scan tool.

I rented a scanner that had ABS. The only ABS codes were related to the wheel speed sensor and were historical as opposed to current. To bleed the ABS pump you need a bi-directional scanner with an ABS Bleed option. The scanner I rented reads coes but didnt have the operational bleed option. Abscate...
