#36 of 535 Carbon build up in the EGR Valve
Feb 24, 2001 (4:51 pm)
I have a 1994 GMC Jimmy 4wd SLE with 183k miles. It has been in the shop 4 times in the last 2 weeks for the same problem. The SES light comes on and the idle becomes very rough. When this happens you lose the power brakes. Each time there has been carbon build up in the EGR valve. My current mechanic, whom I have been using for 11 years, told me there was carbon build up, they cleaned it and the truck ran fine for about 100 miles and started again. Took the truck back and they cleaned it again. We left for vacation the next day it happened again. I called my mechanic and he said to take it to a GMC dealership, and he would reimburse me for all costs. The dealership replaced the EGR valve and the computer. Drove the truck for about 150 miles and it happened again, took it back to the dealership and they cleaned the EGR valve. On they way home, we made it about 700 miles and it started happening again. The truck is now sitting on the carport waiting for AAA to take to the local dealership to have the warranty work done. Does anyone have any ideas as to why this continues to happen? By the way, the did clean the fuel injectors twice in the last 2 weeks. I really love my truck, but can't continue to have to take it to the shop every 100 or so miles. I would purchase another GMC truck in a heart beat since this is the only real problem I have had with the truck.
#37 of 535 banging noise
Feb 27, 2001 (7:46 pm)
I have a 2000 Jimmy that hasn't had any problems. But, it sometimes makes a banging noise that sounds like it is coming from the transmission. It shifts very smoothly when accelerating, but if I let off the gas while building rpm it will bang. For example, if I'm accelerating in 2nd or 3rd gear and the person in front of me puts the brakes on I'll let up on the gas to apply the brakes and it will bang. The service tech. at the dealership said he didn't know what it was but it could be the torque converter. Could that be the answer?
#39 of 535 Oil cooling line recall
Mar 01, 2001 (9:09 am)
I was thinking of putting together a petition towards a recall of the oil cooling lines, since it seems so many have had this problem. I have created an email address: gmcoillinehotmail.com I would like to get one-hundred (100) emails first showing interest in this before I formulate and pass one around. If interested, please send just a short email to that address.
#40 of 535 GMC Jimmy - Problems..Problems..Problems
Mar 01, 2001 (10:16 pm)
After 25 yrs. of Japanese vehicles, my husband convinced me to "Buy American." So bought a brand new fully loaded 1996 GMC Jimmy SLT. It worked pretty well for about 25,000 miles. Service engine soon light would come on periodically. The manual referenced "emissions", so basically ignored it as it would usually go off in a day or two. Well, put $2000 transmission in at 45,000 miles. New thermostat and fan belt around 50,000 miles. The fuel pump ($650) went out at 51,000 miles in rush hour traffic on a busy interstate. That was real fun!!! Recently had the windshield washer problem someone else mentioned. New wiper motor, but also found rear differential leaking so that was corrected at the same time. Recently moved from Washington to Montana in winter snowstorm over three mountain passes. The four-wheel drive worked over the first pass. Took it into the dealer in MT and they said it needs a new "encoder" - $345 just for the part.
Can someone tell me if there is any hope of a recall on the encoder problem? Another message referenced other people having problems with the 4WD.
I can't get rid of this vehicle soon enough. Buy American again? Maybe, but not Chevy or GMC.
#41 of 535 recent rollover accident
Mar 02, 2001 (2:59 pm)
My husband was recently in a rollover accident in a 96 Chevy Blazer The police report states that he went end over end 1 1/2 times and then continued to roll 6 more times before coming to a rest. It is a wonder to me how he lived! He walked away from the accident with only a scrape on his head. I am grateful that we choose the Blazer and am Now looking at the newer Blazer.

Wow, scary. Glad he's ok. I assume he was wearing his seat belt? What happened anyway (or does he remember)?

#43 of 535 1992 S10 Blazer oil leak by lhidalgo
Mar 04, 2001 (8:39 pm)
Leak is coming from the seals between that casting you are looking at (connection for remote mounted filter) and the block. With age and heat the seals get hard and then leak. Good thing is they are cheap to buy at your Chevy dealer. Bad thing is they are hard to replace. Two bolts hold the thing in place and are not hard to get out. getting your hand up there to replace seals and reinstall is tough. I think I had to drop the front drive shaft to get my back in place.
#44 of 535 SES lights, EGR valve, etc.
Mar 04, 2001 (8:44 pm)
I struggled for a long time with my 92 Blazer with Throttle body injection (Z code engine). Rough idle, surging at low throttle settings, stumble under initial acceleration. Diagnosing the SES codes led to EGR valve. I cleaned then replaced the EGR. Turned out the problem was bad throttle position sensor on side of throttle body - tricks computer into misreading throttle setting and misreading exhaust gas condition. Changed it and all was well.
#45 of 535 Retiring much loved 92 Blazer

With 182K miles, I just parked and put a "for sale" sign in window of my 92 Blazer 4dr Sport. Put on lots of miles with no major problems. Normal replacement stuff like shocks, exhaust, lots of brake pads. Other stuff that others have mentioned - crossmember bushings, EGR "gremlins", heater core. The thing always started and ran strong. Always sure-footed in the snow here in northern IL. BTW, put at least 50k miles on Michelin XC LT4's and have agood 10K left - great tires. Just bought 2000 Diamond Edition Jimmy with 5000 miles (guy traded for a new Envoy) and look forward to many more happy GM SUV years.
