One problem related to headlights has been reported for the 2001 GMC Jimmy. The most recently reported issues are listed below.
I previously reported 2 other failures refr to odi number 748064 this time my dome light stayed on and would not shut off I pushed the dome override button several times to shut the light off when I did all of my headlights and dash lights went out. I had to us the override headlight switch to turn on my lights. We took it to the dealer and they ordered a new headlight switch. As of the present time they have replaced my turn signal switch, my ignition switch, and now will be replacing the headlight switch. I feel these problems could endanger other owners. Could someone please contact me and let me know if I am the only person who is having problems so I can tell if this is just my vehicle or are others having problems. Thank you, you may call during the daytime at my work. Again thank you for your help.
