Silly question, I hope but I changed the headlights on my boxster because the passenger side was white where is the driver side was yellow. So I bought the H7 bulb installed it but now my parking lights don’t work unless I’ve got the hazards or the turn signals on when I put on my parking lights both headlights are a dim yellow, and with the main headlights on they’re both white. My question is when I turn on the parking lights shouldn’t just the orange amber lights be on? With my parking lig ...

The one main does attach but the ground does not fit on the tab thats attached to the bracket. Fyi. My horn did work previously. Is this correct or am I doing something wrong with the attached wires?

Monday 12/15/2025 | 2003 | Boxster | Electrical
Over the last couple of weeks,the light selector swith has become finicky. For the various functions of the dial, I can now turn slightly past their previous positions. They do not seem to click into place any longer. I can get lights to function in various positions. My problem is I cannot get the necessary lights to function together, even in the low/high beam position. In this position I can get the headlights to work, the side marker lights, but the rear lights will not work. In the ...

Sunday 12/14/2025 | 1982 | 911 SC | Engine
I see in your previous posts that you recommend and have had great success, as an alternative to pressure feed tensioners, using the latest style normal hydraulic tensioners along with the wider idler sprocket arms, then using a new rebuild kit and filling the tensioner with 60 wt. oil and install tensioner guards. I have been told that tensioner failure is less about the number of miles on the car but has more to do about the age, and ...

READ ANSWERWhat is causing what appears to be an intermittent control board failure?
Friday 12/12/2025 | 2014 | Cayman S | Electronics
At seeming random times, a control board (I think) has a failure that disables PASM and adaptive cruise control (and one other selectable feature I do not remember). The problem has existed for some years. The problem can be cleared by stopping, turning off the car and engine by removing the key and restarting. My guess is that this "reboots" the faulty board.Typically, the car then operates fine for some time, but the fault always recurs given enough time. It sometimes occu ...
READ ANSWERI'm considering buying a 1998 Boxster that seller says needs a new clutch "right away." How much should I expect to pay for a new clutch? Is a Kevlar clutch recommended? Should other parts, such as the flywheel and pressure plate, be replaced at the same time as a reasonable precaution? Thx.
