| Headlights problems |
As I was driving through a snow furry I the snow packed up on the high-beam head lamps that were not in use in the heavy part of the snow storm. These lamp's collected the wet snow and it packed over the lamp so much so when they were activated "no light' of which, would be of use, on wet roads at highway speeds came on the high-beam was of no use at all !!! the problem; when you activate the high-beam the headlamp program is for the "l0w-beam' to go out **** this leaves you the driver with-out any head-lights at all and in this case I mean no light at all . I was traveling at 70 on a 2 lane road in nevada, in a slow lefthand curve when this happened. Thankfully I now the road very will and I drive class a trucks for a living for the passed 18 years so " I' didn't freeze-up when this happened. Sometime soon if not corrected (GMC can do a simple wire re-configureation and solve this problem tomarrow ) somone is going to be killed or injured. I have 1. 75 "million miles' of safe driving under my belt and this is the first time I have ever felt so strong on a problem that I have written anyone. I wrote GMC and the letter I got back does not make me feel they will address this problem at all. Per veh this is such a low cost correction. But if left un-corrected the cost can be so high, not just in money but in lives. Thank you frank b. Rustad cc abc, nbc, cbs, l. A. Times, salt lake tribuine, san francisco-cronicle, .
The driver's side headlight was holding moisture and had to be replaced. Nlm.
