1998 Volvo C70 Problems
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!
Several complaints have been reported regarding Volvo C70 transmission shifting issues. Long shift times between gear shifts, hard shifting, hard downshifting and a loss of transmission operation all together to name a few.
If the issue is minor, a transmission software update may fix this issue so if available, the software should be updated before any repairs are made.
There are several technical service bulletins (TSB's) availab...
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.
The anti-lock brake system (ABS) Control Unit has a high failure rate. When this fault occurs, the ABS light will illuminate and codes may be stored indicating a problem with the ABS Pump Motor, or Wheel Speed Sensors, but the problem is the ABS Control Module.
Other symptoms may include an illuminated Check Engine and transmission shift light. and the speedometer may stop working as well.
Note: The brake system will operate normally...

Hey Great Falls, MT,
If your car is like my 98' C70 it's more than likely that a spring has fallen off of your passenger seat. It's located near the rotating hinge where the seat folds forward/backward.. The spring holds a metal arm against a connection so when the seat is manually put forward the controls dis-engage (safety feature). When the spring falls off the arm becomes loose and no long makes the connect. Run your hand behind the seat along the outer hinge. You'll feel a small metal arm that should be just sort of hanging. If you push it forward u'll hear a click! Try your motor controls if they work, then that's your problem. Can't help u w/ a solution because the spring is almost impossible to get back on.
love this car. just wish i could find out how to make the passenger seat work. looks like there has been a recall on this, can i still bring it in for repair?
The C70 is a fun car to drive! I think it is the first Volvo convertible, and although I had a few problems with the top and the windows, they were addressed under the Volvo warranty. When the sun is out, the C70 is a blast!
