 The air conditioning may have never worked, we hadn't tried it until 10 mths after buying the van. the low coolant light came on and we brought the van to a mechanic who said the repair would cost 800.00. he added stop leak, which worked temporarily. the problem has just reoccured and we have not driven the van since. the abs light had come on in august, we have full use of the brakes, just our abs is not working. we can't afford to fix this. in november of 2001, our fuel pump had to be replaced. i was crossing a busy hwy. here in winnipeg, and the van just died and came to an abrupt halt. i phoned a dealer in winnipeg (vickor chev olds) and the mechanic told me that this happens, sometimes the fuel pump will work for a while and all of a sudden it will malfunction for a couple of weeks. we phoned the used car dealer auto town in winnipeg that we bought the van from and they felt awful, and offered to cover the labor if we paid for the part. the part alone was 400.00

 I have had an ongoing problem with my brakes and traction control. my brakes wear very quickly and smell hot at times. the dealer has told me on many occasions that there is nothing wrong with them. i have gone through 3 sets of brakes , 5 rotors and 3 calipers in 56,000 hwy miles. my low traction light also comes on at speeds of 68 - 72 mph. the dealer tells me to replace my tires to rectify this problem. they report 3 other cases of this trac light going on for no reason. they tell me it is safe to drive my vehicle and that it should not kill cylinders or put on the brakes ander these conditions, however it has killed the cylinders - once at 68 mph on the highway and the other time at approx 30 mph. i do not believe that it is safe for me to drive my family in this vehicle until it is correctly diagnosed and fixed - both the abs and tcs. putiing new tires on this vehicle does not address the route cause of the problem and gm needs to take responsibility for these cars before someone is injured; that is if they haven't been already! please advise as i refuse to pick up my vehicle in this condition. i am ready to contact consumer advocate groups and news stations to warn abouth the safety of these vehicles. help me make gm take responsibility. thank you.

SERVICE BRAKES, HYDRAULIC - ANTILOCK - ABS WARNING LIGHT

 Dt*: the contact stated that the abs light illuminated constantly. there was also a delay in the activation of the abs when the brake was depressed in a normal braking situation. the vehicle was taken to a private repair shop, where the shop determined that the abs module was faulty and needed to be replaced. there were no repairs to the abs system. the contact also expressed that the automatic transmission did not shift gears at the correct rpm level. the vehicle was taken to a separate private repair shop, where the transmission fluid was changed, and the head gasket replaced. the repair did not completely fix the problem.
