My guess its the wiring that goes to the blower motor resistor. I have a 97 Safari and in my case the wire was burnt (the high speed wire is red) I just cleaned the connection and put it back together, I fear that the blower motor may need replacing soon though, I'm sure the wire melted for a reason and my guess is that the blower is not running efficiently and drawing too much juice. The resistor is behind the wiper fluid / raditor resivour. There is a plus that plugs into the resistor and in my case the plug was melted around the high speed (red) wire. I just scraped out the melted plastic and cleaned all connections. High speed has been working for several weeks now. Good luck

Safari / Astro hard to beat

I love my 97 Safari, I've owned it since new and it's got 103,000 miles and living in Michigan with all the salt there is no rust on the body. I can haul 4 x 8 sheets of dry wall, tow my boat, put all my gear inside the van, take the family on vacation with lots of room and comfort and still be able to easily park in a tight parking spot. The gas mileage is better than my 4 x 4 Envoy and there really is not another vehical that compares.

GMC Safari/Astro p0300 missing at 55mph

Hi everyone,
I am having a problem with my 2001 Safari Van. I keep getting the p0300 engine code. I can feel the engine is missing but this is only evident once I get to about 55mph or faster and I maintain a constant speed. Once I feel the engine missing, I can accellerate and the miss disappears. I have replaced the distributor, distributor cap, ignition wires, spark plugs, fuel filter, and applied an injector cleaner in my gas. Still it misses. When it starts missing at say 55mph, the service engine light will begin flashing. If I gently accelerate up to say 70mph, the missing stops during the acceleration and as I approach 70 mph the car is sort of "fooled" into thinking that the missing problem is gone and the service engine light stops blinking and goes out, but when I immediately decelerate to 55mph and maintain that speed, it will begin to flash again. Has anyone out there experienced this missing problem (p0300) and if so, what action did you take to resolve it? Please help. Thank you.
regards,
Doug

The code is a misfire detected code, and if you've replaced everything in the electrical system it may be an injection problem these vans are notorious for the in jectors going bad.I just replaced mine and mine about quit running completely. DLM1

I have a similar problem with my 2000 Chevy Astro van. What I found to be the problem was a broken door jam switch on my sliding door. It's the spring loaded plastic thing that the door pushes in when you close the sliding door. Hopefully, your problem won't be any more complex than this. Whatever the outcome, keep us posted. These are great vans. Mine has 134,000 miles on it. I just had to replace the ignition control module, and other than regular maintenance, it's reliable and running better than ever.

High then low idle, stalling, smelly catalytic converter, oil leakage

hi, I have a 1995 GMC Safari, in the past, my service engine light has come on and the van would seem to miss (chug a bit) going down the road, it quit and the light went off for nearly 6 months, just about 2 weeks ago, the same thing.. Service Engine Soon light comes on occasionally and I could smell the catalytic converter, now it's idling crappy (idles high, nearly stalls, idles high, nearly stalls) and has been difficult to start at times, just today it began to completely stall when coming to a stop or turning at low speeds. I noticed oil dripping from the frame behind the front bumper, i'm not sure where that is coming from or if it has anything to do with the way it has been running but I know it was not leaking before.
Any help would be greatly appreciated.

I't's probally the EGR valve getting pieces of carbon in it.The carbon will break off inside the plenum and get stuck in the EGR valve causing the crappy idle and stalling.The fast cure is putting a screen gasket on the EGR valve but the injectors are probally leaking causing the excessive carbon.These engines run great but the design was flawed from the beginning,the EGR valve is put in a position for every piece of carbon that breaks loose falls in it. I love my ASTRO but hate the engine design and if you pull the plenum you'll find the EGR port almost completely stopped up with carbon. When it gets stuck you can take it on the highway and blow out the carbon that stuck most of the time but this doesn't work forever. You'll end up replacing the injectors and cleaning the plenum in the long run, which is expensive even if you do it your self. Having it done will set you back about 2500.00 to 3000.00 and doing it yourself will cost about 5 to 6 hundred and a few hours labor which I prefer since most garages are crooks and doing it your self you'll know it's all replaced and just not cleaned out to get them by their thirty day warranty. GOOD LUCK DLM1

I found that these engine suffer from condensation in the Distributor Cap. This causes rust under the Rotor mount. The rust flakes off from beneath and magnetizes to the magnetic pick up in the bottom of the distributor causing the random miss fires. A blast of compressed air cleans it out. Treat the Rotor mount with anti rust agent and no more problems! Too simple I know!

Agree with above. Had similar problems on my 91. Light come on, engine gurgling, cat smell. Then go away, but come back. Lurching when cold. Get a new cap and rotor, and replace the two prong (I think) ignition module in there. On your way for under $75..Autozone has the parts. Had to pop the battery cable a few times for everything to reset itself.

I bought mine new and have never had that problem, but it doesn't surprise me these vans have a lot of little idioscencraties. So I guess this is just another one and one I only heard of for the first time and my van is a 95.I love these vans and wish they would have spent a little more time in the engineering because they run great and run forever with proper care and learning all the little idioscencraties so you can know how to deal with them as they come along.I recently had a problem with mine losing all ignition power which was the first and figured it was from the main bulkhead for the wiring that plugs in behind the battery,the main power lead was pulling so much power it was melting the plastic plug which I've seen on a lot of vehicles.I pulled it out cleaned it with contact clener and scraped it with a small knife and crimped the connector to fit tighter and it fixed the problem.The main problem I' ve seen on these vans with the vortec is the injectors going bad and causing carbon to build up in the plenum and then breaking off a tiny piece at a time and going straight in the EGR valve causing the loping and missing and usally a strong smell which is usally unbrnt fuel due to flooding. I hope he can fix it with a new rotor and distributor because that's the first thing I tried with mine but it just kept getting worst to the point it was undrivable.You're right usally a miss at idle and higher speeds are usally attributed to cap,rotor or wires and I hope this cures his problem but I think he said that was a 94 or 95 van and if the injectors aren't leaking it's a miracle for the astro miracle book,it would really surprise me. those injectors are connected with all cheap plastic lines with o-rings which is usally what leaks instead of the injectors themselves,but once you spend several hours taking one apart it's not worth the extra headache to just replace them and find out the injectors were shot to and have to redo it.
