But this would have me going over the vehicle electrical connections. I'm not writing this is it but it's the FREE procedure I want to see if it helps. I start at the fuse box and using the fuse puller tool and be sure I can see what's what with good lighting I pull one fuse at a time and put it back into the same spot. That done I wait and see if that helped. If not I try other electrical plugs and do same. If a plug is stubborn I don't press my luck.
It's most likely a poor connection. But where?
I have 2009 Acura MDX tech pkg. when the car is first started in cold weather all electrical components flash on and off. Head lights, dash lights, etc. power locks don’t work either. After 10- minutes the car warms up and everything works like it should. I replaced the battery and had the alternator checked. Negative wire on the battery seems ok too. What could it be ? Ty.
