#1 of 2 99 Jimmy All lights dimming in and out by otra Nov 28, 2007 (10:23 pm)
i have a 99 gmc jimmy with 135k on it. i have done a bunch of work on it. altanator = $120 fuel pump = $500 water pump = $75 LF and RF hubs = $150ea Smog pump = $450 Door pins = $50ea and regular maitnence of course... repairs seem to be more cost effective then buying a new car, so.... My latest problem is the headlights, parking lights and all the interior lights pulsate all at the same time and dim in and out while im driving. its kind of hypnotic. anyway, the altinator is only a year old. so im wondering if this is a result of a bad voltage regulator. i was under the impression that the voltage regulator was an internal component of the altinator. therefore it has been replaced. is there a external voltage regulator that can be replaced or am i on the wrong path all togeather here?
