Monte Carlo :: 2003 - AC Blows Warm From Left Vents But Cold From Right
Jun 27, 2007
The air coming out the right front vents is cold; but, the air coming out the left front vents (driver's side) is warm. Sliding left ac slider switch up and down did no good. Considered fuse, but both left and right AC controls run through same fuse. Suspect bad motor for left side plenum duct, or bad connection, or faulty vacuum at motor (if motor is vacuum actuated). Considering removing dash cover to see if I can find the motor, but not sure how to remove dash cover, or even if that's the way to find the motor.

I took my Monte in for the annual Missouri Safety Inspection. Note: I had no known problems with my 2003 Monte SS 117K Miles. After the inspection, which passed, I was informed of a variety of problems: Intake Manifold Gasket Replacement, Valve Cover Gasket w/Intake replacement, Thermostat w/Intake Removal, Fuel Injector O-Rings w/Intake Removal.
My question is should I have all of this done? It's not cheap..roughly 1000 bucks. I know very little about this and I don't want to just tell my mechanic to do it without some research. Are these common problems with Monte's of this age/mileage and just part of the cost of owning this car. I am the original owner and have avoiding costly repairs/maintenance..it's been a great car.

The engine fan in my 2003 MC SS doesn't seem to be working and the car is starting to overheat. The other fan, which I think is the A/C fan seems to be working okay. I know nothing about cars and before I take this to a mechanic. I do not want to go somewhere and get totally ripped off. So it would be nice if I appear to know what I am talking about... when I take it to the mechanic.

I have a 95 Monte Carlo LS it has 53,000 miles and When I go to give it gas it hesitates and the rpm goes down and then I let off the gas and do it slowly and its fine. Why this is happening all of a sudden. And my check engine light is on.

1997 Monte Carlo, 3.1 liter, 3rd engine, I have oil in the coolant and it uses 1 qt of oil every 3,00 miles. No smoke from the exhaust. What is causing this???

The rear roof vents on my wife's GX470 only blows (non-cold) air, even though the rear controls are set for the coldest setting and the front is blowing ice cold. There are no error messages.
It's clear the rear is not working properly, yet there are no error messages.

Turned the key on my 2002 MC SS, V6, 3.8L, and the Intake Manifold exploded.
Intake Manifold Exploding on a GM V6, 3.8L? It sounded like a 12ga shotgun. Fortunately no one was looking into the engine compartment at the time as they likely would have been killed given the amount of shrapnel from this explosion. Note that the explosion was powerful enough to blow off the oil cap, which is screwed on with very thick threads.
The vehicle was at my mechanics at time and in his forty years he's not seen an intake manifold explode save for those residing on Top Fuel or Funny Cars.

I recently (about a year ago) got a 2000 Monte Carlo, great car, runs good, just one issue. Lately, when I accelerate it shakes in the front end, I let off the gas, the shaking stops, some days are worse than others. Some people have told me its the CVS, or the axle, or the motor mounts. Is this common with a 2000.

The car takes off from a stop as it should. However, it shifts hard from 2nd to 3rd gear and that's when it stumbles and doesn't want to accelerate. It'll go if you press pedal at least halfway down. It runs great other than that. It only has 60k.

My 2006 Monte Carlo has been making a strange 'tweet' sound. I only notice it when the car is off. It's just a single 'tweet', a minute or so will pass, then it does it again. What could this be? I'm worried it's something expensive.

I have an '08 350 with less than 82K miles. My problem is the AC. The vents on the passenger side blow out cool air and all the vents on the driver's side blow out hot air. Even the vents in the backseat, the left one blows hot air and the right one blows cool (my son informed me of this as I hadn't even checked). As you can imagine it's very uncomfortable driving around in this CA heat every day, especially since the driver side vent in the center cannot be completely closed. What could cause this?

I think I've joined the ranks of the no overdrive in our Monte club. Bought the car last summer, 184K on the odometer. Previous owner was original owner. Said trans was always strong. Took the car for a spin Saturday. Previously, no OD issues. It's cold out. Pulled up to a light to get out onto main road. Right turn on red. accelerated normally, but noticed a long hold in 1st before shifting into second. Never saw it before, so was paying attention at the next light, which was right away. Accelerated again, and again a long hesitation going from 1st to second.
Next light is right away again. Light turns green, car shifts normally and I drive it about 10 miles. No issues. I paid particular attention to it going into overdrive, and it did. Arrive a junk yard. Got the part I wanted. Spent about an hour in there. Came back out and started home. Car shifted ok, but did not want to go into overdrive. Thought to myself, well, maybe it's cold. Drove some more. Nope. Never wants to go to overdrive anymore. It does shift from 1-2-3-4 ok. I've heard about the stripped spline in the output shaft, but I was wondering if there is another controller somewhere inside, or outside of the trans that could be causing this issue. When I am in OD and in 4 gear and driving at about 50 MPH and I shift it to D, I feel it shift into 3rd. I plan on getting it diagnosed, but was wondering what you all are thinking.

I have a problem on the blower motor and i think its something besides the blower motor going out it works fine most of the time but occasionally it does not come on when this occurs I noticed that the cruise light is flashing in the dash and when this is occurring you can push the on/off switch in the steering wheel and the light does nothing. Now whenever the blower motor works properly everything with the cruise functions properly no light in the dash and when turning on/off switch works properly also no noise coming from blower motor ( bearing ) sounds fine. would a bad BCM cause this or am i looking in wrong direction ???

My 99 Monte Carlo LS has a problem with the ac and the heater being stuck in the defrost mode. The heater and the ac work fine but it won't switch to anything else. I heard this could be a vacuum prob. I found a hose that runs from the top of the upper intake manifold. It goes to a T then one end to the firewall and the broken end is by the battery. I don't know where the broken end goes.

I have a 2005 monte ss supercharged and the tranny is doing some serious banging and knocking..flywheel is tight..no metal shavings in fluid or around tranny. The noise goes away then I rev the engine or driving. But if I floor it it makes a grinding sound at high rpm..
