Nissan Repair: dimming of lights, nissan maxima, loose connections

Question
Hi I have a 2000 Nissan maxima ..just had all 6 coils replaced and a new alternator put in along with a new battery.(had to drive to MN from MA. Now in MN  last night there was frost  on the inside of my windows and as i worked the windows the lights seemed to dim. Can you give me some insight  on what the problem could be to look for.
Thanks !

Answer
Karen,

Go to Autozone or Checker and get a free electrical inspection.  They will load test your car in the parking lot and let you know if the new alternator is defective and not charging the car fully or if the new battery is not working properly.  Also, they will let you know if there are any loose connections that could cause the problem.
