When i turn my HVAC fan switch on I hear a loud ticking coming from the engine and it starts to run rough. When I turn the fan off the rough idle disappears. Also the #5 setting on my fan switch only works sometimes and the backlighting flickers. Any solutions?

Replying to: gregearn (Dec 10, 2007 7:51 am) As for the #5 fan setting - I think its a separate issue - blower resistor going bad perhaps - cheap part about $ 20, its located behind the blower on the passenger side front. Easy repair, very common failure on the Venture. The flickering seems to be common on the Venture and usually is cured by a new alternator - it probably flickers more because the fan running on high speed is a pretty big electrical draw. Just some things to check right off the bat - post more details and hopefully I can help you further. John

I have not decided if I want to spend that much money yet. The sound I am hearing when I turn the fan on is coming from the engine itself. Is there a vacuum line connected to the HVAC that could be causing this?

Replying to: gregearn (Dec 10, 2007 11:08 am) Are you sure the click isn't coming from the compressor? On some cars, the compressor kicks on when the selector is in the defrost setting, not sure if this is the case in the Venture, if so, then there's an electrical connector on the compressor that you could unplug...will have to check on the wife's (2000 as well) when I get home, maybe that's the click or does it not matter which position the vents are in? Is it the same click? Let me know...I'll have to admit that you may have me stumped....I've never known an alternator to make a click...usually a grinding or metal on metal scraping sound...I just can't think of anything that would click in an engine when you turn on the fan. With the hood up can you get a general idea of the direction of the click?

2003 Chevy Venture 3.4 liter There is a loud knocking when first started that lightens after running for awhile but is still there. The oil is fine, no lights come on, seems to run fine. Any ideas anyone? Never had a moments problem with this van in the four years we've had it. Only has 97xxx miles and has had the oil changed religously.

Replying to: cujo57 (Jan 06, 2008 3:12 pm) Does it eventually go away?? All of the 3.4 V6 in the Ventures make a metallic tapping sound when they first start which goes away in a few minutes. Its nothing to worry about, the lifters in these motors are pretty noisy at startup. I think if you keep up the maintenance the way you've been doing you should have no problems. |

I recently started having problems with my van stalling and also running rough..chugging..usually between 60-80kph.The problem only happens when the van is warmed up.I had it to my mechanic who checked the fuel pump..which was fine..changed the fuel filter and also put the van on a diagnostic tester.Even when the van was chugging and stalling no codes came up on the tester.Both him and I are at a loss.I thought firts maybe bad gas..water in the gas..but i put in methyl hydrtae and hi-test gas and the problem coninues...any idea?

Replying to: chewson (Jan 31, 2008 10:44 am) get a digital multimeter, check the resistance on the ignition modules (located in back on top) between the two towers on each (towers meaning where the spark plug wires connect to) the resistance should be 5000-7000 ohms - if its above or below, you've got a bad ignition coil...and make sure the posts are clean Run a bottle of fuel injector cleaner through it (Techron recommended) Get a can of MAF sensor cleaner and follow the instructions. Just a couple of things I would try right off the bat... No codes at all? No check engine light? Interesting...
