Thank you mate! You don't know how much this helped me. I tried to find this lump from below the car but couldn't do it to save my life. Definitely I need to remove the air filter housing first and then try cleaning the drain. If not possible from the engine bay will try again from below the car. This will be the first thing I do on the weekend. I think that the evaporator has never been cleaned from the inside. Car has original condenser and radiator. I cleaned the radiator with a soft brush too. Changed coolant (not as a try to service this AC problem but as a general service). Doesn't leak, doesn't need coolant, engine temperatures stay at the middle, always. About the 22 year old car and service - I'm afraid, It's just how I am. I like to have my cars in the best state possible (if it isn't something too expensive, also I'm a junkyard connoisseur :D). I took care of all the rust, freshly painted some parts, all the plastic trims are almost "like new". I have another, newer, car which I use for longer distances, but I like this Škoda and it's 1.9 SDi for daily commute, because it's a hardworking donkey. It is lazy for sure, but also doesn't have a DPF, simpler EGR, no costly fixes, very fuel efficient, it just goes and goes and goes...

Thank you for your patience with me and for taking your time to make a couple of pictures. About the AC system in the car - Compressor was taken off and checked, It was said that it is good. New compressor clutch was installed, new PAG oil put. AC system was vacuumed and filled with new refrigerant. After one year the refrigerant level was checked and it isn't leaking refrigerant (10% max as it is supposed to). The AC condenser fan was replaced. The evaporator was cleaned from the inside with the AC foam cleaner and a fresh cabin filter was installed. Now the AC is mostly working but sometimes is not? In, for example, 33 degrees Celsius, after taking the car from the garage (not it being in the sun, baking) I, alone in the car, need to turn the AC (fans) on at least 3rd, often 4th speed to make the driving tolerable. Sometimes AC is blowing absolute arctic cold and I use no more the 2nd fan speed. I've noticed that when I turn my AC on, the car, when in neutral, tends to have random RPM spikes which, I presume, correspond to the compressor cycling. I understand that the compressor turns off when it reaches the set temperature but these RPM spikes randomly happen. For example, 3 times in 5 minutes when there is absolutely no chance the the AC achieved the set temperature (car was parked in the sun). I'm waiting for my VCDS cables to arrive and I'll try to scan the codes hoping that maybe a sensor or two is faulty. Maybe interior temperature one, maybe AC high pressure switch, etc...

I've looked at those pictures literally, minimum, 10 times in the last 7 days and watched many videos that I could find. I think that those pictures are relevant in the MK2+ models, but not in the MK1's. As I've said, I cannot see the lump from the engine bay because I think that there isn't one. Also, I would have tried to find the problematic lump, but as I've said, I have the intake manifold in front of the insulation which makes it difficult. It's the 1.9 SDi and the intake manifold is very big. I supplied the picture of the engine bay I found online for illustration. There isn't enough space to even reach the insulation with palm of my hand. About the condensation evaporating part - I really don't know, I know that as long as I remember I had the wet spot below the car after AC was running and now there is nothing there, not even after parking the car.

Hello, I have some problems with AC in my Fabia 2003 1.9 SDi and after changing many parts on it's AC system I figured that I don't see the wet (condensation) spot below the car anymore. I presume that the evaporator/drain is dirty and that it cannot properly drain the condensation and that's why I have inconsistent AC. I tried to clean the evaporator drain tube from the engine bay but it cannot be reached because of the intake manifold and thermal protection panels. I tried it from the pit below the car but it's the same story, so I got the idea to take the glove box out and roll the carpet down to try cleaning the evaporator and hoses. So I'm asking is it possible? Did anyone did it before? Where is the drain located? How hard is to roll the carpet? I now taking the glove box is easy. Any advice is appreciated. Thanks

Hello, I have a problem with my Fabia Combi 2003 1.9 SDi that is bothering me for a long time. I've spent much money on service but still haven't fixed the issue. Only, and I say ONLY, when I turn my AC "On" I have random engine RPM spikes which (I presume) correspond to a cycling AC Compressor. I went to a mechanic who told me to go and see an AC Specialist. AC specialist took down and inspected my compressor, said that it is okay, changed compressor's clutch (said it's slipping), put fresh PAG oil in it, regassed the system and sent me on way. AC still didn't blow cold and I still had random RPM spikes while idling with my AC on. I've noticed that the faster I drive the better my AC works. I presumed that the condenser fan might be faulty. After some time I went again to another AC Specialist who showed me that my AC condenser fan isn't working. I've replaced the fan, told him to look at the level of refrigerant in the system (didn't need more refrigerant) and after the service AC started blowing colder. Not freezing cold (5-6-7 degrees Celsius as it should), but reasonably colder. Then I decided to clean the AC system with a foam cleaner and change the cabin filter. I did that couple of days ago, and I think that the AC blows even colder but I didn't have the chance to test it properly because now the weather is overcast with rain so the temperatures aren't that high. Will see results the first time the temperature goes over 33-34 degrees Celsius. This weekend I plan to use another can of foam cleaner to try to clean the AC evaporator through the condensation drain hoping that it will have some effect on cooling (I presume it was never cleaned). After servicing all of these parts I'm still left with random RPM fluctuations when my AC is on. I've ordered VCDS diagnostics cable and I'm currently waiting for it to arrive and then I'll try to scan and see if there are any error codes. I'm totally guessing, but could it be that the AC Pressure Switch (G65 Error Code) is the problem? Maybe it's false readings cause the AC compressor cycling, or could it be the alternator? My headlights work, power steering is sometimes heavy (power steering fluid level is as it should be; also I think that the Fabia is slightly nitpicky about the quality of tires), but the battery is charging normally. If anybody had similar problems and solved them or has some idea what it might be - be free to write. Many thanks. Boslo

Hello fellow Škoda owners! The thing I need is actually quite easy, only I don't have the parts numbers. I supplied the picture (found online) with pointing arrows for easier explanation. Those two rubber grommets in the corners of the engine bay and a clamp/clip for what is, I presume, air temperature sensor (I just want to make sure that I order the right clamp because I see many similar online). If not evident, the car is Fabia Mk1 1.9SDi. Cheers.

Hello fellow Škoda owners, I need some help with diagnosing a strange sound that can be heard on startup of my Škoda Fabia MK1 Combi, 1.9 SDi. It's left hand drive vehicle and the sound can be heard from the right side of the hood, behind the passenger's side dashboard. The sound can be heard mostly on startup of the car, especially in the morning in the cold weather. It's like an electrical hum, it's not squealing or brushing, it's like that low noise which you hear when you blood pressure is high. It stops after some time and then it doesn't start again till the next morning, no matter how many times I start my car that day. Car needs to to be parked for some time for the sound to be heard. I suspect that maybe it's the alternator's bearings/brushes, but I'm not sure. My logic is that the cold weather depletes more of the battery power so the alternator works more on startup till it fills the battery. Problem is that it's random so I would like to narrow it down before going to a mechanic because it's very hard to replicate. Any advice is appreciated. Many thanks.
