2003 Volvo C70 Problems

Electrical problems from bad battery cable

The battery B+ cable has problems with the terminal end necessitating replacement. Symptoms may include no start, cranks wont start, warning lights coming on and other odd electrical issues. The B+ cable end is located in the engine compartment fuse box near the drivers side shock tower.

Door Window Regulator May Fail

Door window regulator failures have been reported. These vehicles have a very complex door window mechanism that can be very difficult to adjust properly after installing a new window regulator. This can lead to air leaks, wind noise, and a door that doesn't open or close properly. This is a good time to find an experienced Volvo mechanic!

Knocking Noise From The Front Suspension Going Over Bumps

Knocking noises going over bumps can be caused by worn sway bar end links. These end links have small ball joints that become loose and rattle. Replacement is the only fix.
