Hi all. This might just be me. I've had my 2002 406 for 2 years now with no problems so far but as of late it's started to taken just a fraction longer turning over before it starts. I thought maybe glow plugs, then when I start reading about them there's not a lot in the user manual. When I turn on the ignition the glow plug light does not come on, then someone told me that unless the temp is at a certain level then they don't come on, but I would have thought that the dash should at least light up to let you know they are working even if they don't heat up. Is this correct, and if it is, is there any way for me to test them just so I know that they will work when they're needed. Thanks in advance.
