1994 Chevrolet Astro Problems

What owners report

Owners of this model year most often describe two recurring problems: windshield wipers that stop working intermittently, and brake complaints that range from an ABS warning light to a pedal that goes to the floor. Torsion bar breakage on the front suspension is also reported repeatedly, often while the van is parked or moving slowly. Many of the wiper complaints note the van was excluded from a wiper-motor recall that covered nearby model years, based on its VIN.

1. 1
   Visibility (wipers, defrost, mirrors)

   Windshield wipers stop working intermittently

   • 75 complaints (23%)
   • median 110,000 mi at 10.0 yrs old (17 state mileage)
   • 1 mention a crash, fire or injury
   • filed 1997–2010

   Complaints describe wipers that quit without warning, sometimes mid-stroke in rain, and sometimes fail to start at all when the switch is turned on. Several owners say tapping or wiggling the wiper motor or its wiring gets them moving again temporarily, and others were told a module or motor needed replacement. Many note that a wiper-motor recall covered other Astro model years but their van was not included because of its VIN. Reported across a wide mileage range, from roughly 11,000 to 150,000 miles, with many filed at 70,000-140,000 miles, usually in rain or winter weather.

   What to check: Operate the wipers at every speed and in the intermittent setting, and ask whether the wiper motor, pulse module or wiring has been replaced. Because coverage varied by VIN, ask a dealer to run the VIN and confirm whether any wiper campaign applies.

   2 excerpts from owner complaints in NHTSA records

   “Failure of windshield wiper motor circuit board connector due to faulty design, I.e. Insufficient support of soldered wires, leading to fatigue crack of solder joints, then failure of motor operation. Two of two other owners of early 90's astros I spoke to had had the same complaint, and one of those had heard of others.”

   NHTSA complaint #10050819, filed 2003-12, 150,000 miles

   “Front windshield wiper motor stops intermittently, especially in inclement weather. Restarting requires lightly tapping the motor with the wiper switch in the on position. Current GM recall (#03023) only includes 95-97 astros. Gm told me they expect 94's & 98's to be included in recall in near future. Owners with valid repair receipts will be reimbursed, according to my GM call.”

   Brakes

   Brake pedal or ABS problems; long stopping distance

   • 83 complaints (25%)
   • median 140,000 mi at 12.0 yrs old (3 state mileage, few)
   • 15 mention a crash, fire or injury
   • filed 1995–2011

   Complaints describe the ABS warning light staying on, the brake pedal sinking or going to the floor, and longer-than-expected stopping distances, often on wet or snowy roads. Some owners say a dealer diagnosed a failed ABS computer or could not reproduce the problem, and one report describes a burst metal brake line at the left front. Others describe the pedal being difficult to re-apply quickly after the foot slips off. Reported mostly between about 100,000 and 162,000 miles, frequently in wet or snowy conditions, with some earlier ABS-light reports under 15,000 miles.

   1 related service bulletin

   What to check: Ask for brake service records, check that the ABS lamp comes on at start-up and goes out, and have the brake lines and pedal feel inspected. A service bulletin describes a brake pedal that moves down or self-applies during near-full-lock turns on these vans, so ask whether that bulletin work was ever performed.

   “On november 21st, 2011, I was driving my Astro van on a straight road. The vehicle in front of me applied their brakes. I also applied my brakes, but my foot slipped off the brake pedal. I attempted 4 times in a panicked state to try and re-apply my brakes with no success. I struck the vehicle in front of me. After considering what had happened that day and looking at the brake pedal size in the vehicle it is no wonder I couldn't readilly re-apply the brake. I measured the brake pedal surface area. It is approximately 4 sq. Inches. …”

   NHTSA complaint #10436820, filed 2011-11, 162,000 miles

   “Drove out of driveway and ABS brake light went on and would not go off. Shut car down and restarted. Light went off but as I drove out, ABS light went back on. Took to dealer said it was the ABS computer that failed and that I would have to replace it because it was out of warranty . Regular brakes are functioning properly, but I do not have ABS brakes. Estimated cost to replace ABS computer $1300-$1400.”

   Suspension

   Front torsion bar breaks, front end drops

   • 34 complaints (10%)
   • median 151,975 mi at 13.8 yrs old (4 state mileage, few)
   • filed 1998–2008

   Complaints describe one or both front torsion bars snapping, leaving the front corner of the van resting on the tire, most often discovered while the vehicle was parked in a driveway. Some owners link the breakage to corrosion and debris collecting where the bar mounts into the frame crossmember, and several note replacement parts were on back order. A few reports mention loss of steering control when the bar failed while driving. Reported mostly between about 20 mph and highway speeds on vans with high mileage, many at 140,000-180,000 miles, and one owner noted an earlier bar replacement near 80,000 miles.

   What to check: Inspect both torsion bars and their mounting sockets in the crossmember for rust, cracking or debris, and check that the van sits level at both front corners. Ask whether either bar has been replaced and whether the replacement used the updated design.

   “We own a 1994 chevy Astro van. Fortunately, it was sitting in our driveway when one of the torsion bars broke, dropping the van down onto the front left tire. If this had happened while we were driving the van with our family, it could have been disastrous. Two days later, the other torsion bar broke, again in our driveway. …”

   NHTSA complaint #10164660, filed 2006-08, 126,112 miles

   “This is the second time I will have to replace the torsion bar on this 1994 chevy Astro awd van. The first time was about 4 years ago. I have done a search and there are hundreds if not thousands of reports of the torsion bars failing without warning, resulting in bottoming of the suspension. Fortunately, it failed when I was parked both times it has failed but could have been devastating if I was on the highway.”

   Engine cooling

   Rough idle and stalling from clogged EGR valve

   • 12 complaints (4%)
   • median 102,000 mi at 11.3 yrs old (3 state mileage, few)
   • filed 1996–2008

   Complaints describe the 4.3L engine running rough, idling poorly and stalling at stops because carbon builds up in the EGR valve. One owner reports removing and clearing the valve repeatedly, and another says a dealer replaced the valve several times and cleaned it on other visits without a lasting fix. Reported on high-mileage vans, around 100,000-150,000 miles in the sample.

   1 related service bulletin

   What to check: Ask whether the EGR valve has been cleaned or replaced and whether the rough-idle symptom returns. Listen for a rough or hunting idle at a stop during a test drive.

   “For all of you 1994 Chevrolet Astro owners and any others that have the older 4.3l vortec engine. I have the solution to your legr valve carbon cloging problem. My 1994 ext van has 150,000 miles and I had been getting the rough idle and stalling when at a stop light problem. It has done this before to me every 6months or so and I just pulled off my EGR valve, knock out the carbon chunk that is stuck in it and 20 min later im on my way. Well it has come back bad and it is cloging every 20 miles with lots of carbon chunks. …”

   NHTSA complaint #10062518, filed 2004-03, 150,000 miles

   “When driving engine runs rough and acts like it wants to cut off. Also, EGR valve gets clogged with carbon on a regular basis. Dealer has replaced EGR valve 3 times, and cleaned it 4 times.”

   NHTSA complaint #8004280, filed 2002-02

Buying note. These vans are well into high mileage, so the practical questions are maintenance history and condition: have the wipers, brakes and front torsion bars been serviced, and do the ABS lamp and airbag lamp behave correctly. A pre-purchase inspection focused on the front suspension mounts, brake lines and wiper operation is worthwhile.
