[carlo77777]

hey whats up everybody i have a 2000 jaguar s type 3.0 i bought it a week ago for a really good deal. The only thing wrong with the car is that the heater is not sending out hot air ? has this happend to anyone else ? and how do i fix it ? please get back to me. the heater works but no hot air.

I think you have an air bubble in the cooling system of the engine, i dont know exactly how the system works because it also has airconditioning, but the air bubble prevents hot water to stream through the heater.

So you probably need to fill the radiator reservoir with some coolant and then bleed the radiator (i hope that this is good english ;))

I dont know if there is somewhere an airvalve, but if it is, it is most likely fitted on top of the radiator.I did it a long time on an old car with no aircon, but i filled the radiator reservoir, started the engine and turned the airvalve open till there only gushed water out, and i shaked the car a little bit, but i doubt that worked ;)

Good luck

Good chance it is a clogged/defective heater control valve. About $225 from suppliers. Don't know where it is located. Haven't looked. Doesn't look too complicated to change. Didn't have time to bother with it myself. Cost me $500 +/- to have a "European Auto" shop diagnose and replace.

Look in your coolant recovery bottle. If the level is not lesss than 2 inches from the cap, low coolant level will prevent the heater from working. If it is low, you may have a cracked bottle. Coolant would leak out from the area just below the driver's feet, onto the ground.

Just noticed same issue with my 2000 jaguar 3.0.
How did you fix it?

I also have not had heat in my 2000 3.0. I just checked my coolant reservoir and it was low. After filling, I got nice warm air! Hopefully, you will have the same luck.

I am assuming you already checked your reservoir level, but just in case; these are the exact symptoms I had and as soon as I filled the reservoir up, I had hot air. I hope this is your problem and you simply didn't see my earlier post. Good Luck!

Out of now where this morning my air conditioning started blowing hot air. The fuse is blown in the engine compartment for the air conditioning clutch, but when I replace it the same thing happens. Please help with any ideas.

Well I had almost the same problem.I got a 2000 s type 3.0.When the car is idle or goin not more than 35 40 mph the heat and ac won't work, as soon as I pass 40 mph they both work fine.The problem is the vacum door of the heatin-ac system.I don't know more about it but if anyone does please feel free to let us know
