#3 of 5 95 Astro Rear AC has quit by kwyx66 Nov 18, 2007 (4:43 pm)
On my 95 Astro CL with 150k miles, the rear air conditioning recently stopped working -- really bad news in Texas, even in fall or winter. I have checked individual components including: the rear blower fan, the resistor, the wiring harness from fuse panel to the rear fan, the fuse, and the dash panel switch -- all tested fine. Using a meter, I determined that there is no 12v power on the hot side of the fuse at the fuse panel. Is it possible that I have blown a fusible link on the back side of the fuse panel? Before I pull the fuse panel, are there any other suggested troubleshooting steps I should try? Thx !

Replying to: canadianmom (Oct 31, 2007 7:43 am) Re your recent posting about hard starting and gas smell: Over the past 12 years I have had similar symptoms on the '95 Astro-CL that I bought new in summer of 1995. The diagnosis: bad fuel injector / intake unit. The fix: replace. The first one (replaced at the dealer) was on me; subsequent replacements were on the dealer, covered completely under the GoodWrench Service Plus program. Good luck.

Replying to: canadianmom (Oct 31, 2007 6:39 am) Sounds like injectors leaking, or regulator, or bad o-rings in nut kit, which are the plastic fuel lines inside the plenum that feed the fuel to the regulator. The bad part if you have this repaired at a garage you'll put put out about $2500.00 to $3500.00 in parts and labor. I would do it myself if I were you if you have some basic machanical knowledge and are pretty good with tools this is not a real hard job. It'll take a few hours and about $500.00 in parts to do the job completely, but doing it yourself you make sure it's done right and can give you a chance to clean out the EGR valve ports and plenum and get rid of the bad idle problem that you were having nine chances out of ten. If I decided to do it I would replace the injectors and the nut kit which is a dealer item and put a screened gasket on the EGR valve before putting it back together, they make a gasket now with a screen in it to stop carbon from getting in the EGR valve which cause the rough idling. I recently redone mine and went from 12 to 14 miles a gallon to 19 to 20 miles a gallon. so it's well worth the effort in fuel saving alone. Good Luck DLM1954
