Volvo - S90 :: AC Went From Cold To Hot Almost Instantly While Driving
Aug 7, 2011
I have a 1998 Volvo S90. I usually have to charge the a/c once a year to keep it cold. Today while driving the a/c went from cold to hot almost instantly. I turned it off, waited a minute and turned it back on. Cold just like normal. Two minutes later, hot air again. Turned it off again, waited a few minutes, turned it on, cold air but only for about 30 seconds. This was all done while driving. What might be causing this?

I have an '89 740 wagon, Bosch ignition. It will not start. If I spray starter fluid, it will fire, then immediately die. I have replaced already both fuel pumps, noise suppressor/fuel injector relay, fuel pump relays.
I installed a fuse in the fuse box, which was empty when I purchased the car. And the engine instantly died. It did start up when the fuse was removed, and I drove it back across country. The idle got worse until it died and would not start back home.

I have an 89 Volvo 244 DL series. I have had a complete tune-up, and oil change just recently. Battery works great, plenty of voltage, even had the fuel injection cleaned out.
Problem is the car starts right up when it is cold, however, after driving it and let it set for an hour the car starts up slower and immediately it stalls out. I do it again and the same thing happens and then I leave my foot on the pedal to keep it running at a higher idle for a bit and then place into a gear & it goes without any hesitation. If by chance I do not leave foot on pedal and put it in whatever gear it immediately stalls out. I have driven Volvo's for years, from the 70's to what I have currently. I never had encounter anything like this and have dealt with many other issues and this one has me baffled.

In hot weather, after hard driving for an hour or more, usually (but not always) with a/c running, the engine on my 1998 Almera (a/k/a N15 or Pulsar) stops. The idiot lights come on and if the radio or CD player was on, it shuts off. I can immediately shift to neutral, turn the key, and the engine restarts almost instantaneously, with no difficulty. (I've gotten quite good at this, and can restart the car within a couple seconds, even while I'm coasting as a result of the original engine shutoff.)No matter how hard I drive the car, the problem happens ONLY in hot weather. I've had the beast worked on by competent Nissan mechanics, but no one has been able to figure out the cause.

I own a 2005 volvo s40 i5. Recently I noticed that my dashboard gets extremely hot after just couple minutes of driving. Originally I thought this has something to do with the car's black interior. However, my suspicion changed when I noticed that the dashboard became very hot even on cold rainy days. (Below 60 degrees) This presented couple issues while driving.
1) On cold days, my windshield would fog up very easily.
2) on hot days, the cabin of the car can be intolerably hot. Both of my check engine light and my airbag warning lights are on.
However, auto mechanics cannot diagnose the problem because they can't get a reading through the diagnostic scanner. They said most likely the car has a electrical short somewhere.
What the problem is? Could it be an electrical short that cause excessive heat in the dash? Maybe the engine heat is venting into the dashboard? Fix?

My car is blowing cold air but no heat at all. I checked the codes and it's throwing a B1 1-3-1. It's also throwing a A7 1-2-2. a buddy of mine is a mechanic but not too familiar with Volvo's. But he said that he thinks the B1 1-3-1 Driver's side air duct short is the problem. Is this the problem and how do I fix it?

We have an 04 Volvo V40 which won't idle when it's cold out, especially at altitude. Not all the time- it seems to be somewhat random, but it is getting more frequent. Our mechanic has replaced the MAP and TCV sensors and that didn't make any difference. What to try next? It recently passed an emissions test, so when it idles, it runs fine.

There are two issues with my 1994 Volvo 940 (automatic). They may or may not be related, but that is why I'm asking.
1) When the engine is cold and at a stop sign the engine will rev up and down. After the engine warms up, the issue goes away.
2) Also when the engine is cold, when taking off from a stop the car doesn't seem to want to go.
You can mash the gas all the was down and it just kind of slowly gains speed. Eventually (5-10 seconds) it will act like normal and go and shift fine. I hope that is enough info and makes sense. I'm just trying to see what the problem could be and how to fix it.

I have a 2005 VOLVO TRACTOR, Autoshift, Cummins ISX. Recently the Dashboard only works at "cold" condition, after 5~20 minutes of starting the engine, the information Display shows up: check lights control module, check vehicle ECU, check air bag, check climate module, finally show "check datalink". Speedmetre, RPM, oil pressure, water temperature gauges and gear position are all dead, only Fuel, Air, Pressure and Turbo gauges work. We have replaced new dashboard, but nothing changed. And we checked J1939 communication wire OHMS is 60 at either back of dashboard plugs and data link. All modules are working good except information module. When dash was out, we did connect the laptop via datalink. We could communicate with ECU normally. The problem looks like the dashboard is so sensitive and easily quits working. We had checked batteries and main ground cables and all fuses. We did the test, after removing all lights control module fuses, ABS module fuse, climate fuse etc., the dashboard sometimes works

I have a 1983 Volvo GL 240 Auto trans. I've owned this car for a very long time ~20 years and have never had a problem with it. Since mid Autumn this year (currently Winter in Australia) when starting the car after it has been raining, left overnight in the cold or it is a particularly moist day the car will not start properly.
What happens is the car will start and I accelerate to take off the car will lose significant revs, stall and die. If I can get it out from the driveway and onto the road continuously for 5 minutes the car will run fine for the rest of the day.
But if I stop (to a halt) during this period and try to accelerate the car will again lose revs, stall and die. It is very hard from this point to get the car started again as the same thing continues to happen.
I have changed the spark plug leads, engine oil and trans fluid.

Xc 90 D5 2.4 2005 diesel, will not start when it's cold (below +5 degrees), If I use the pre heater for 3 min it starts fine.
I have checked the injectors (leak back test). I checked the glow plugs and they all glow red when I turn on the ignition.
No error codes (Volvo has checked)

My '91 240 races when turned on when motor cold, colder it is the moreso, especially in Park and Neutral till it calms down It's happening under 60 degrees Fahrenheit and big time under 32. Sometimes turning steering wheel sharply will stop this. Is this ECU? Transmission? Belts? There seems too show excess transmission fluid on the dipstick, by the way lately, which may have been that way from accidental overfill and may not be related t this insane racing issue.)

My mechanic installed a battery about a year and I have to get my battery charged each time the weather gets cold or snowy. I have had the battery charged 2 times this month.I have had this same problem last year calling motor clubs to charge my battery. My car is snowed in and shovel is stuck in my trunk because it will not open because my car wont start. I do not even know if there is a warrantee on the battery ...it may be a used battery.

my 2007 3.2 s80, 75 K miles, will not respond to accelerator for the first 1-2 miles after a cold start, then runs fine, no check engine light has shown. Per shop recommendation switched to 92 octane x3tanks, then replaced fuel sensor, neither solved.

I have a 1994 Volvo 940 and have previously owned a 740 for many years. I've only owned this car for about 1 month. The car appears to have been well cared for. Doesn't leak a drop of any fluids, everything works, and mostly a really nice old car. What happens is that it idles rough when it's cold. In fact, I have to pump the gas pedal to keep it going. When I first start off, the performance is less than what it should be too. Once it get warm, it mostly runs fine.
I have so far replaced, the Plugs, Wires, Cap & Rotor. All the vacuum lines, crank position sensor, Air Mass Meter and the fuel filter and most all the fuel lines too. The Fuel Pump Relay was replaced but I removed it and saw a few cold solders and fixed those but no changes in performance. Before I replaced the Air Mass Meter I brought it to local shop and they returned a readout of 2-3-2 which I'm understanding means running too lean. That's why I replaced the Air Mass Meter. (I did notice a big improvement once I replaced the Air Mass Meter too.) It was interesting that when I replaced the Distributor Cap, I noticed like black carbon in there and I'm not sure what could cause that. Although, I did find the previous plugs were not all the same. Three of them were high spark performance plugs and one was just normal
I pulled the Idle Air Control Valve and plugged one side to ground and the other side to 12V and noticed the flapper moving when powered on/off. The previous owner told me he replaced both fuel pumps about two years ago. It also looks like the fuel regulator valve is mostly new.
I'm guessing now that I have a problem with the Idle Air Control Valve or perhaps the Fuel Temp Sensor under the intake manifold. I purchased the Fuel Temp Sensor and just have not installed it yet. I really don't want to remove the intake manifold but I know it's not going to be that bad. I know that it could be carbon build up on the intake valves but I'm not quite convinced yet. I put some fuel cleaner in the tank to see if that works and so far nothing yet. The car only has 150K on it and I was told that during the owner before me did do highway driving.
When it's warm, the car does run very very well. The idle is still a bit quirky even when warm. For instance, when I power on the A/C, the idle RPM doesn't increase like I expect that it should. (It did on my 740) ... I'm still thinking maybe it's the Idle Air Control Valve too. Perhaps it's intermittent or do I understand that they can gradually open and gradually close?

This 1996 (220KM) car will run fine (perfect)for about ten minutes from cold (I'm talking -5 C)then starts to misfire when warmed up. Difficult to pull away (automatic) from a stop. Sound like its missing on two cylinders. Really chunters.
Installed new plugs, wires, cap, rotor, coil,filter. Don't know what to check next. Car will work at speed but I can feel it missing. Gun it and it will go. Doesn't appear to be a fuel problem.

Our 1997 850GL wagon with 160k miles has persisently noisy valves. At considerable cost, we replaced the hydraulic valve lifters with new ones from Volvo. Noise persists. Increased oil viscosity, now at a ridiculous 15W40. Also using an oil additive to further increase viscosity. Little if any noise when engine is cold but once warm, much valve clicking. We change oil religiously and keep oil topped up.

I have a few questions about my 1987 240 DL volvo. First, it's been making a funny, whiny, rattling noise (mostly centered in the dashboard area) whenever it get's too cold outside. I know that taking apart a dashboard on an old volvo is really hard, but it the noise worth the effort? So far I've noticed no problems with how the car runs. Second, there is a small button on the left side of the gear changer, when a press it a lighted forward arrow appears under my speedometer. What is this button for?
