2003 Chevrolet Suburban HVAC blower not fully functional on all blower speeds..service bulletin 11046, April 2010..Chevrolet has known defect wiring connector and electrical terminals of relay resistor module as described in service bulletin which results in blower motor not functioning on certain or all blower speeds setting. GM has issued special coverage adjustment for up to 10 yrs per bulletin but refuses coverage purportedly based on my vehicle not being in the special coverage VIN: Two phone calls to customer service resulted in a hang up, put on hold and not returning to the call, and upon escalating the call to joy, the supervisor refusing to further assist...and refusing to escalate the call further explaining no manager is "likely" available, we've told you your answer....GM case #71-107-8244378 2nd issue with electrical; instrumentation cluster fails to work properly and digital display which indicates whether you are in park, reverse neutral drive (gear) dims or goes out completely. Same problem I had on 2005 Chevrolet Suburban 1500. Both vehicles they have refused to fix. 2003 had special coverage 07187 to repair this condition but the previous owner was not properly notified to fix this condition during the manufacture special coverage period.L they know it exist but once again are using any excuse to do the proper thing and fix the problem. Also reported under 71-107-8244378 request NHTSA and appropriate agencies further investigate these matters and hold GM accountable do not let GM continue to skirt recall repairs for known problems by narrow defining which vehicles they have to fix. Recalls should cover all vehicles that have identified safety issue and GM should facestiff punishment to encourage them to voluntarily fix problems rather than stonewall, stall, avoid, and make it more difficult than fixing the problem.
