Replying to: michael8735 (Mar 03, 2006 9:01 pm)  I'm having the same problem with my 2003 Buick rendezvous the fans not turning on unless the a/c is on, I'm in constant fear of overheating, can someone with this similar problem tell me how they got this problem fixed or what was the cause. can you believe i got no help with this problem from Buick headquarters, they act oblivious to any major problems, especially when it comes to overheating. but i know different i have replaced window motor, starter, more than one kind of gasket for the engine and transmission, hub assemblies, wheel barrings, frequent brake jobs, complete a/c system replaced, engine censers, I'm going to stay away from GM products next time, i just cant chance another round of this, very very disappointed.

I had to replace the thermastate and the antifreeze. I also found out that my gages freaked out when the engine oil was old or low. The check engine light would come on and the car would stall. It spent two weeks in three different shops and no one could tell us why it was stalling out. It turned out to be low oil. I wish you good luck and I am never going to buy a GM car or truck again.

At that point, only ONE fan is supposed to come on, until somewhere around 235*F. If you aren't driving in heavy stop and go traffic, or towing, the fans would only come on once in a while. If turning on the A/C immediately turns on one of the fans, that's a good sign the fans are working.

Replying to: oneofhismen (Aug 12, 2009 4:37 am) As far as the oil - the gages (sic) have NO way to know if your oil is "old". If your check engine light came on because your oil was old, it was extremely old, abusively so. I am NOT saying you abused your car - I am saying you do not get a Check Engine light due to old oil. As far as the car stalling because the oil was LOW, how long had it been since you checked your oil level? You know, with the dipstick? Any car, even a brand new one should be checked periodically, at least monthly. |

Replying to: bxd (Aug 12, 2009 5:43 am)  my RDV has not reached the red area yet , but am still curious if someone else had this repaid and what was the fix, anyway my RDV always sat with a still temperature and didn't fluctuate from 1/4 hot and the 1/2 way mark on my vehicle, but lately i have noticed that its reaching close to the 3/4 hot and the fan is not kicking in, its at the shop at this time and i was told one of the cooling fans was week, and replacing it will take care of the problem, I'm hoping the mechanic is correct, the fan is about $29 to $39 dollars plus installation, i was told this vehicle is hard to diagnose when it has cooling issues or fan issues, i couldn't take it to the dealers, they charge well over $300(rip off), I'm still trying to recoup from my last A/C repair

this 2003 rendezvous is still not working properly , i don't understand why this vehicle is giving me so many problems, when it was well, i mean well maintained, for those people that don't want to hear about the crap GM makes, they are crap, never had these kind of lists of extended problems through out the years, you figure with 83,000 miles is not alot of mileage for all these problems, at this time, i just picked it up for a cooling fan repair yesterday , the fans are fixed but the temperature gage still climbs near the 3/4 hot when idling or in park, and the temperature sits steady only when i run it with the a/c on. throwing more money away that i don't have today , thanks GM, hearing from other people that have GM products, tell me they have issues to

Replying to: sal72 (Aug 12, 2009 7:46 am) Whoever told you this car is "hard to diagnose" is either lying or doesn't know what they are doing. Sorry to be so blunt. The engines in the RDV (both 3.4 and 3.5) have been put into millions of cars/trucks/vans since their initial design came out in the late 1980's. The engine has been tuned, adjusted, enlarged, more controllers, etc., but it started its life back in 1988 as a 2.8 V6. The two fans come on in two stages, at two different temperatures. They can be turned on manually by a tech to test them, at any temperature. It's one of the easiest things to troubleshoot. Does the fan now come on? Does it appear to spin fast? If "yes" and "yes" and the car still sits at 3/4 on the temp gauge, they didn't test the fan correctly, and just threw parts at your car.  I'd be disappointed too. Question: if it gets to 3/4 hot and you begin driving at a steady speed, at least 40mph or even take it on the highway, does the temp drop down again? If so, the fans are still part of the problem most likely. If the temp does not drop during steady, higher speed driving, then the cooling system is not working efficiently. Either the radiator needs a cleanout or there might be air in the system. Has any maintenance been done to the car lately? If so perhaps they didn't purge all the air.

Alright I bought my '03 RDV CXL as a totaled vehicle with some front end damage back in 04-05 with 23K miles on it. After I repaired it I have put on about 80K miles and I have replaced the alternator, and both wheel bearings(I chalk this up to the wreck), and tires(God forbid). This car has been a rock solid vehicle that have have taken hunting (nothing truly off-road, but in the middle of alfalfa and wheat fields) and on several 2K+ road trips. I have done all of the oil changes and rotations on time and it has been a great car. So those of you that complain about your car acting up 2 sentences after saying you've ran it with low fluids, its not the car's fault it didn't add or change the oil. Anyways, my A/C has been leaking refrigerant, I got it checked and filled once and it leaked out in <3 days. The guy that checked it put it under vacuum for 20 minutes and it kept pressure. When I brought it back in he couldn't remember if he put dye in my system(major oversight if he didn't since it obviously wasn't holding pressure) and he couldn't see any evidence of dye leaking in the engine compartment. He brought up that it could be the evaporator, and well I don't feel like tearing my entire dash out. So my question is what are the chances that the evaporator did start leaking? I'm trying to get it into another place with a sniffer to see if they can find the leak with out relying on the dye. |
