#3267 of 3449 Re: Anti-theft system [mrurl] by kmb6013 Sep 12, 2008 (8:15 am)
Replying to: mrurl (Feb 01, 2001 12:48 pm) the anti-theft system is full of bugs. there is only one way to fix it and that's by bypassing the system. however, the only way to do that is by having a remote starter put in. i went through the same thing and replaced the ignition and switch but it still happened. after i put the remote starter in i never had the problem again and that was 2 years ago.

Replying to: dbraganza (Sep 10, 2008 7:52 am) Slop in the steering could be a lot of things, as mentioned. Also, if 4WD the axle hubs and wheel bearings may need to be replaced. Thats a lot of miles, and most people don't lube the front end parts very regularly, so a lot of wear is not suprising. I would go to a front end alignment shop first, preferably non-chain, and have them check the alignment, usually $25 or so. Stick around while they do it, and they can show you where the free-play is. Once you know what is needed, then you can get some estimates on repairs. For parts, I've been using Rock Auto, online store, good prices, quick shipping, usually name brand parts. I don't have any vested interest in the store, just good results. Tie rod ends are less than $10, not too tough to do at home, ball joints less than $20 each, much harder to do at home.
#3269 of 3449 Diagonstic by duntov Sep 16, 2008 (3:05 pm)
Unfortunately, most repair shops will charge you a diagontic fee and it may be as much as $90. It may be waived if the shop does the work, but then you must trust them to install the better quality parts and not just charge you for the better parts and install junk parts made of Chineseium. Rock Auto is an excellent source of good quality name brand parts and I use them quite often in my restorations. However, but you must intstall the Rock Auto parts yourself. If there is a job above my pay grade, I have a younger gauy I found on Craigs List who will install my parts while i watch. I pay him $40 per hour and I still come out cheaper than taking it to a crooked repair shop. I would estimate that 85% of the auto repair shops are crooks. That is the only way they can make a decent profit.

I have a 99 blazer 4x4 that I put in 4 low and the light on the dash just kept blinking, althought the vehicle felt like it was in low I don't believe the front was working. I then put it in 4 high and the light wouldn'tstop flashing also. when I put it back in 2 high all was wll. I tried this a couple of times and had the same result. Whaddaya think?

Replying to: chevguy1 (Sep 21, 2008 5:24 am) Your Blazer needs vacuum pressure from the manifold to shift into 4wd. So I'd start by checking the vacuum lines from the manifold.

Replying to: toleson (Dec 15, 2007 11:17 pm) I would change the dimmer/headlight switch. i had no dash lights only my aftermarket radio.

Replying to: chevguy1 (Sep 21, 2008 5:24 am) The first thing to check is that the front drive axle is engaging. The most common failure is the vacuum that activates it. There is a vacuum line that goes to the shift mechanism passes under the battery on its way to the front axle. Fumes tend to disintegrate this line. Crawl under the front while someone inside switches from 2wd to 4wd and see if the actuator moves. Unplug the vacuum line and see if you feel vacuum. If not,replace the line.    If this is OK, get the Haynes or Chilton manual (I have both) to see how the shifter motor is attached.

I may have a slightly bent front lower control arm that may be causing alignment problems. If so, could this be adjusted to some degree? Replies to this message: johnss10 (Sep 24, 2008 12:32 pm)
#3275 of 3449 Re: 91 Blazer lower control arm [scruffielad] by johnss10 Sep 24, 2008 (12:32 pm)
Replying to: scruffielad (Sep 23, 2008 8:50 am) I think the answer is Maybe. It depends on direction and how "slight" the damage is. The only way to know is to take it to an alignment shop. I would go to a non-chain (individually owned) shop and have them check it.

I took my Blazer to a buddy for him to look at and they told me it was the over drive bearing. I have never heard of an over drive bearing They told me that my whole engine had to be replaced and that just didn't sound right to me. Because Overdrive has everything to do with the transmission now if there is such thing as over drive bearing it would be in the gear box or somewhere in the tranny right? and how would I fix it Replies to this message: jlflemmons (Sep 26, 2008 11:11 am) chevygirl77 (Sep 26, 2008 11:42 am) jlflemmons (Sep 29, 2008 10:02 am)
