Device, now reported by Chevrolet dealership to be automatic climate control thermostat,located directly over driver's head in 2005 Chevrolet Tahoe continuously (while vehicle is running) emits 100+/- milligauss of electrical charge. My exposure to this during first week of my ownership of vehicle after my July 21, 2008, purchase caused me to have debilitating headaches and tinnitus; also, my memory seems to be less sharp than before exposure. Two Chevrolet service departments and I identified the devices causing high radiation exposure to my head,and selling dealer disconnected thermostat;disconnecting thermostat results in front defroster,and all heat and air conditioning systems being rendered virtually uncontrollable. Originally selling dealer offered to relocate the thermostat away from my head,but dealer later retracted that offer. Chevrolet customer service looked into the issue of the thermostat emitting high level of radiation and reported to me the thermostat/device is performing according to specification and may not be relocated. With thermostat connected,I get debilitating headaches and tinnitus,the related long term physiological ramifications of which I do not know. If the thermostat is disconnected,my inability to control temperature and airflow inside the passenger compartment render the vehicle unsafe to drive under many weather conditions. Postscript: it occurs to me that the radiation exposure from the Tahoe thermostat seems many times higher than the radiation exposure associated with cell phone usage;and the thermostat radiation is emitted continually while driving. I am informed that for a short period of time several years ago,Volvo offered for sale in europe,a retrofit package to ground out high radiation levels in its vehicles.

Defroster works intermittently. When the consumer gets the defroster to come on it does not clear the entire windshield. While driving on the highway, it stops working. Consumer has to pull off of the highway and wait for it to start working again. Manufacturer was notified, but not willing to do anything.

The blower has gone twice (first time was Jan 2003) since owning vehicle, it suddenly stops working especially at low temperatures (under 32f). Defogger system does not work. Dealership has fixed problem twice. Back blower works fine.

Three individuals at my work have had the knob fail which prevents the defroster from working creating a hazard with iced windows. Dealer was smug and noted that they replace lots of these. The failure of the knob is internal to the module and prevents an easy inexpensive fix. Repair is 285. 00.

Heating system in the back of vehicle was not properly heating vehicle, throwing out cold air. Contacted dealer, and dealer said there was nothing they can do because there was a defect in manufacturing of vehicle .

On Dec 24, 1997 for the first time in chicago, ill, my sister in law and I were on our way back home from thier company x-mas party. There first real storm of the year winter that is. On our way back we could not get the vehicle warm the windows were frosted right up my sister in law was helpnig me scrap the ice off the inside of the windshield. All windows were froz in the inside with three kids in back covered with blankets. I thought may be I was doing something wrong because this was the first time I really drove it anywhere. We went really slow all other vehicles were going slow or already off road stuck I had the vehicle in 4wd so we plowed right through everything. We got home and I told my husband he was in another vehicle with my brother I wanted my child in my vehicle because of the weather being so bad I figured he is safer in a bigger vehicle. When my husband went out he started the vehicle up and did not believe me nor my brother. A few days later we left and sure enough on our way home to michigan not but a few miles the heat quit working . We stopped about 5 hours later to warm up and eat we went back out vehicle had heat again not for long thou. We then in return brought the vehicle into dealership right away. They replaced the control head. This is the first time if more info please right or call please help us!.
