So when i start my car my lights and fans just turn off and on...? And the speedo and tec don't work. If i sit there it doesn't do it as much once it heats up.. and out of what may be luck it all started after i got a flat.. but the biggest thing is that the Speedo doesn't work, the tec jumps when i first start the car but then it goes to zero..checked all the fuses and the battery connections,...also the VDC and slip lights stay on... Any one have any idea's...?
