#939 of 3676 '99 Blazer, Air Conditioner, Brakes, and Autotrac
Sep 02, 2004 (12:12 pm)
My first post here! I have a 1999, Chevrolet Blazer, LS, 4WD, 2D with 77k miles. Any feedback or suggestions regarding my 3 conditions would be appreciated!
1. Air conditioner was working fine this summer. Then after sitting for 4 days, the air conditioner does not produce any cold air. Period. I checked the fuses in the dash and they appear fine.
2. Hard to believe, but I still have the original disc brakes. (Knock on wood) Any suggestions regarding replacement? The dealer wanted some ABSURD amount to replace the disc brakes. No weird noises yet, but they braking is "soft" compared to original condition.
3. The Autotrac system is not shifting properly. Now that Winter is approaching this is a concern! I cannot shift out of 2WD using the Autotrac pushbuttons. The 4W Hi and 4W Lo buttons will "blink" but not become steady in color to indicate the transition. I can tell when driving that the Blazer remains in 2WD when the 4W Hi is blinking. Sounds like trouble to me.
Thank you all!

I think I can help with problem #3. My 2001 Blazer had the same problem last winter. Took it to the dealer and it was a bad connector for the electronic 4x4 system. Mine was still under warranty, but I think it was only around $50 and they had the car for maybe an hour.

If your wiper problem is just the circuit board, it should cost less than $100 to replace. The part runs about $55 or $60, labor should not be much, it takes about 20 minutes on a slow day to replace.

I haven't had a chance to read these posts for a while. Regarding post 925 by "ault", I had the same situation. It turned out to be the hood hinge. The hole for the hinge bolt is quite a bit larger than the bolt and the hood moves up and down making a "clunking" sound when going over rough pavement. There was a Service Bulletin issued for this and the number is 01-08-63-001. The "fix" is to remove the hinge bolt, install a cone shaped washer and reinstall the bolt. I purchased the washers and did the job myself in about 10 minutes. The part number for the washers is 12383460 and I paid $5.18 for two. I haven't had the "clunking for two and a half years. Credit for the info goes to Alldata.

I don't think you can replace just the circuit board as it is not a separate part. It comes as part of the "wiper assembly" or something. Anyway, I was quoted approx. $300 for the whole thing, parts (~$200) and labor (~$100).

My service engine light went on and I had to replace air intake valve.
My ABS and Parking Brake indicators stayed on. Checked sensors. Replaced parking brake module, very costly. Lights no longer on.
Fuel guage gone wacky as with other posts.
What could it be?
Whinning sound, sounds like tires although tires are in good shape. What could that be?
68,000km. Any ideas for cheap solutions? Thanks!

Your soft brake pedal condition is most likely due to air in the brake lines. If you don't regularly flush your brake fluid, you're bound to have the problem. Brake fluid naturally absorbs ambient moisture. Over time, the oxygen component of the water separates into air bubbles. Some manufacturers (Honda for one) now recommend annual flushing of the brake lines. It not only alleviates a spongy brake pedal, but also protects the valves in the anti lock brake module and enhances brake reaction time. A cheap piece of maintenance with a high return value.

out of our 1999 Blazer (bought as leftover in 9/99). Have done routine manitenance and replaced alternator. Truck just turned 40K, and plan about 5K per year. Any suggestions as to preventative maintenance at this time?
