Hey guys (and gals). I just took my mom's 1999 Chevrolet Blazer into a local dealer to get a tranny flush and oil change. While in the service bay, they informed me that the oil cooler lines were leaking, there was a vacuum hose leak under the dash that effects the HVAC system, and the serpentine belt was cracked. The car only has 63K on the odometer. Are these problems normal? I can understand the serp. belt, but the oil cooler lines?!? They wanted $400 to do those. I declined, needless to say. My grandmother's 2001 Blazer had the same problem, but replaced the lines with aluminum lines, I believe. Shouldn't this be a recall?? Or is it?? Any help is appreciated. Thanks a lot!

I think GM uses a vacuum module to operate the air vent system to direct the flow, for heat,defrost,a/c etc...if you have a leaky line it could affect the air volumn and direction.

Thanks for the reply. It's very helpful. That leaky vacuum line on the HVAC system was effecting directional air flow (i.e. flow would not change from defrost to defrost/feet when the dial was changed).
How can the oil cooler lines hurt an engine? Is it just because coolant leaks or is there any other problems that may arise?

I believe GM had a TSB (technical service bulletin) on the oil cooler lines a couple of years ago. As I recall, I believe the lines and fittings were replaced on the vehicles affected. I'm not sure if it covered your problem, and I'm also not sure whether the '99 model year was included. You may want to call the GM customer service line or check with a local dealer.

I found a posting on the net as to the procedure to reset the code. It sounds like a no brainer but my buddy said be careful you may just mess up the computer memory and end up with a big service bill. Has anyone tried to re program their remotes , with what results.?

did they make a 2000 lumina? I thought the last one was in 99. The Impala came out in 2000. small point. Blazer, Jimmy, for the value you can't go wrong. Did you buy it?
#862 of 3676 Control arm rubbing on brake hose
Nov 13, 2003 (12:48 pm)
A warning/observation/prompt for other experiences...
I have a 2002 Jimmy SLS, around 35000 km's, and had to stop suddenly to avoid an accident recently. I drove away from that, luckily very close to home, as I suddenly had almost no brakes at all. I had to push all the way to the floor to get even a little response, and that was not the most confidence insipring. Fluid was leaking from the left front, and I had it towed to the dealer. After some investigation, it was determined that a control arm had been rubbing against a brake hose, and the sudden application had caused it to burst.
Which prompts some questions:
-has anyone else ever heard of this (ie control arm rubbing against brake hose) - I searched this forum and found nothing
-why the heck did all four brakes fail? Only one hose burst (left front). When I asked at the service counter I was told, 2nd-hand, by a teenager that it was something to do with it bursting before/after (they couldn't remember) the distributor; the computer subsequently decided (!) to shut off ALL the brakes. Good thing I wasn't doing 100k's + on a highway when I figured out they weren't working...! I have a hard time believing they shut off by design.
