Toyota - Corolla :: 2003 - Air Conditioner Does Not Turn On
Jul 29, 2012
The AC in my 03 Corolla stopped working. A Mechanic originally diagnosed it as low in Refrigerant - brought it up to full charge. Stopped working again in a couple of days. I took it to a different mechanic who confirmed that there was no leak and it had a full charge. He could make the compressor come on by shorting a connector (located near the compressor). Otherwise the compressor does not come on when the AC is turned on from the switch inside. The blower fan works OK. The fuse is OK. The relay works OK.
The mechanic tells me that the only thing could be that the PCU ( the computer?) has gone bad and that only the dealer can replace it and reprogram it. The car has done 120,000 miles and I am wondering if its worth spending that much money to get it fixed -- that is if the PCU is the real problem. Could it be something else? Is there a way to get a used PCU and have it installed by a mechanic other than the dealer?

My 89 Corolla started overheating when I turn on the AC. If I don't use the AC, the temp. is fine. 2-3 min. after turning on AC, temp. gauge rises and I must turn off AC. My husband, a devout CT listener has some mechanical skills & ck'd it out. He replaced the fan relay, but that didn't fix it. History: the 1st time it happened, the AC was on and blowing cool air, suddenly, the air wasn't cool and I noticed the temp. rising and turned off the AC. I stopped and checked the radiator fluid and it was low, so filled the overflow with coolant. Drove home (30 min.) and it was fine.
A week later, same thing - I'm on the freeway, air is blowing cool, then not and heats up. Ck'd radiator - fluid level is fine. Problem was somewhat intermittent as it wasn't happening 'all the time'. Yesterday, same thing again on the way to see the dentist 40 min. out in mid-afternoon sweltering heat. Had to drive there and back with no AC - quite miserable. Replaced the thermostat not too long ago and the radiator also had to be replaced year before last. I have health issues and really can't handle the heat and fumes and must have AC in this climate. We can't afford to take it to a mechanic. If this car goes, them I'm car-less. It's a great car and keeps on going - 240,000+ miles.

My wife's '01 Corolla is having trouble starting. It doesn't turn over. At first I thought it might be the alternator, but when I prime it by pushing the gas, it starts right up. I'm thinking fuel pump or fuel line. It was also having some catalytic converter / 02 sensor issues, so wondering if that could be it too.

I have a 1996 Toyota Corolla (5-speed, manual transmission) that has never had any problems until the past month or so. About 80% of the time now, the car does not turn over at all upon turning the key first thing in the morning. The dash light indicators (seat belt, brake, etc) come on, but that's ALL. No sounds come from the engine. I turn the key all the way back to the starting position and immediately try again, and the engine starts right up on the second try, almost every time (a couple times it has taken a third try). It will start the first time the rest of the day.
Three things to note that may or may not be related:
1. About 6 months ago, a large tree branch fell on the hood, causing some damage to both front fenders and some dings in the hood.
2. It seems to mainly occur on mornings following a rainstorm, but I can't be sure that is always the case.
3. My key is the original, and occasionally will not unlock the doors (manual locks) on the first try, but when this happens, the key will not turn at all until I mess with it for a bit.

My 2009 Toyota Matrix will turn over but wont start. I cant figure out what is causing this. So far I have replaced the battery ( Just in case ) I checked the spark plugs , they are good , If I try and start it a couple of times I can sometimes get it to start but its really rough sounding and dies instantly even if I give it gas. I also hear the fuel pump engaging so I don't think that is it. I put 5 gallons of premium gas in the tank just to make sure she didn't get some bad gas since she was almost on empty. I am lost at what to do now.
I just went over 60k miles so no warranty anymore.

Car is 2000 Corolla with 58k miles. Today, I had my hazard signals on while parked when suddenly....they stopped blinking. The signal lights in the dash just stay on...they do not blink. I also verified that both front and rear lights also turns on...it just doesn't blink.
The corolla has a fuse box under the hood in the drivers side. Here is the schematic for the fusebox: [URL] .....
From what little I know about mechanics/electricity, can I just pull the wiper fuse and put it into the turn signal fuse while I wait for a new fuse? Do I need to disconnect the battery?
How to confirm this is the part I'm suppose to install: [URL] ....

I have a 94 Corolla with 239 K After pulling into my drive way and turning the car off I went back to start it ..Car turned over but no start ...ok backed the car out of the drive used the other car . Came back the next day car started pulled it back into the driveway ....Went to start it again later that day ..no start this happened for a couple of days ..It would start and then it wouldn’t..... Checked the fuel pump ..its not working ..The relay is good ..
There is power coming into the fuel pump but. Only one lead with power ...I power the fuel pump direct and it works ...I take it to a shop to have them look at it and they say I have no spark and that there is power going to my fuel pump ..he said there was power but he did not say if the fuel pump worked ...The gas gauge works but the fuel pump still .
So the fuel pump works if i power it direct and I have no spark ..so I could change the distributor & coil and go back to checking ground wires to the fuel pump BUT anything else going on that might be causing these issues. The car was running perfect before this happened.

I have a 98 Toyota Corolla, manual transmission. When I come to a hard stop, or make a hard turn, the engine either stalls or almost stalls. I've had it serviced lately with new plugs and wires, oil change and fuel system cleaning. The engine idles fine when you start it and are just sitting there. The problem seems to come with stopping hard or turning while quickly slowing, when the clutch is engaged. If I am able to hit the gas I can keep it running and then it runs fine.

The car's engine just stopped while driving on highway, then would not turn over, nothing.Took for repair, said battery had bad cell or something, still under warranty, replaced.Fixed a few other things that were overdue, spark plugs, wires.
Okay. Next day, took the car on a few city driving short trips. While going across town on hot 85 degree day w/ ac on, it died again. Don't remember any lights coming on, didn't last time either. I think the AC died first then car died. Wouldn't make a peep. Right in middle of heavy traffic. When police came couldn't even steer. There might have been a slight weird noise which I thought was the ac making trouble right before it stopped, can't describe it really.
Had it hauled to shop again. It runs fine for them so far. They are still working on it.What in heck could it be? All belts were replaced a few years ago, car has always run well, never any major repairs just maintenance. It has about 133,000 miles on it. It has a clutch.

so I noticed that my muffler started to turn brownish on my 2014 Corolla. I am worried because my car only has only 480 miles. Is this normal, should I be worried?

A friend of mine owns a 2002 Toyota Corolla with around 100k miles on it and it has some sporadic problems. Once in a blue moon the engine light comes on because of a misfire and seems to be around the same time it is humid and wet out (suggesting spark plug wires). However it recently sat overnight, after a slow rain, and would not even turn over the next day. The lights are not dimmed in the car but there is only a faint hum when the key is turned. What is wrong?

My 2011 Toyota Matrix (with Moon roof) driver side interior light won't turn off. It's in the off position. I've checked all doors and closed them properly and turned the dimmer switch down.

I have a 2003 Toyota Corolla CE manual transmission with 431,000 (not a typo) miles on it. About 7 weeks ago I noticed that when I turn on my high-beams after driving for awhile, the car dies for a few seconds. All lights go out, radio stops, engine stops and then it starts up again as if nothing happened. It will just do it once in about a half-hour time frame. I can switch the high-beams on and off repeatedly afterwards and it doesn't do it again. I have to drive for about a half-hour before it will do it again. I usually hear a slight pop sound when it does it.
A month later I noticed that if I parked it after driving for awhile, like at a gas pump, and get back in it, it acts as if the battery is dead for a few seconds. If I step on the clutch or open and close the driver door, the car comes back on. It appears that the battery was disconnected. The CD pops out of the player and all the radio station settings are gone. One morning last week I got in, and it had happened during the night. The CD was out, station settings gone, and the clock was 6.5 hours off.
I have had the car to a Toyota repair center 3 times. They have checked fuses, battery, battery cables, grounds, alternator, tensioner, looked for rodent nests, squirrels and I don't know what-all, etc. They can't find what is wrong. I am scared to drive it, but I depend on it. I commute 200 miles/day. I won't leave anything important in the car because I am afraid it will catch fire. I am scared I am going to have a wreck, too, with no lights and no power steering suddenly.

2000 Corolla - "growling" noise on the passenger side of the engine / stops when I turn the steering wheel - no loss of PS fluid (I also flushed the system) - which bearing(s) might be bad...?

I own a 2001 Toyota Echo. When I turned on the air conditioner, the fan would run, but there was no cooling. I took it to the Toyota dealer for repair, and the problem was a bad compressor. The compressor was repaired and the a/c worked. Twelve days later, the a/c would not cool. I took it back to the dealer, and the problem was "Found clutch melted to AC compressor." Fortunately, the repair was still under warranty, so there was no extra charge. I had never heard of the "magnetic clutch assembly" melting itself to the AC compressor.

I have an 8 year old 2004 Toyota Sienna LE minivan. This past weekend I tried running the air conditioner when the temperature was in the low 80's (F) outside. Unfortunately, the AC only blew hot air, even though I drove a pretty long distance with the AC on.
I think the refrigerant has leaked out and is depleted. Whether or not I should attempt to recharge the AC by myself with my neighbor's assistance (he has all of the gear for recharging the refrigerant) or if this is a job that is better left to a professional.
Also, if I do attempt the job by myself, would it be better to try and seal the leaks with a dedicated sealant first, or should I use the canned refrigerant that also contains some kind of sealant?

I have a 2003 toyota corolla. For the past year I have not been able to pump a full tank of gas without the pump automatically shutting off. It has progressed to the point where I have to stand at the pump and continually restart the pump as it clicks off over and over and over.

The Corolla was starting yesterday, but slow. Went and bought a new battery and replaced the old one. Cleaned both cables very good. Now all the lights work, everything electrical works fine, but the car will not turn over, not a click!

I have a 1996 Toyota Tacoma, 5 speed manual pickup.
Occasionally I use the air conditioner. I'll be driving along and it's working fine but then it stops putting out cold air. I pulled into the mechanic one day and confirmed that when it is not putting out cold air, the compressor still seems to be running.
If I go into a store for about 15 minutes and then come out again, it works again. What might be happening?
