2000 ols intrique headlights dimming and heater fan slowing while driving. only does it when its cold outside. i believe its the regulator in the alt. seems like it was a common issue with these cars. any other ideas? also is there anyone who rebuilds these reasonably or that i could get a kit to do it myself in edmonton? seems kinda steep to replace the whole unit when its just the regulator and a new alt. is over 300.00 bucks. thats abot 6 sled tanks full of fuel when you add in the taxes.any ideas would be great.
