Will someone help me with my no start problem and A/C heating problem?

It's a 97 VW Jetta GLS. It will crank but not start when it's warm outside. It starts up fine in the morning but after work when I go to get in it, if it's warm (at least 60 degrees or warmer) it won't want to start without me hitting the gas a few times. Also, the A/C and heater will not blow out on 1. The heater will blow out on 2, 3, and 4. When the A/C is pressed in it doesn't blow on 1 but the A/C light is on and when I switch it to 2, 3, or 4 the light goes off and it just blows out air from outside. Anyone ever had any of these problems? I brought it to my mechanic and he can't figure out the A/C problem and he couldn't duplicate the starting problem b/c once it is started it will start right back up until it has sat for a while in the heat. He seems to think getting a complete tune up will help solve the problem. It has about 110k miles on it, if that helps.

well, the hard start when warm could be caused by a few things.


It actually might be as easy as replacing the gas cap.


1. check your fuel pressure. the next time your car doesnt start, dont give it gas at all, then pop the hood, and check to see if you have fuel pressure. there is a rail that all the fuel injectors (they look like "y") are connected too, and at the end of this rail is a bicycle tire valve. Take a ball point pen, and depress the inner metal pin lightly. If you have gas that shoots out, then you have fuel pressure. if you dont, then theres the problem, you have a leak in the system causing the pressure to fall. try just replacing the gas cap, more then likely that will cure the problem.


2. check the cold start injector. here is a picture:

to check it, next time your car doesnt start, unplug that wiring harness, then try to start the car again. If it starts right up, then the valve is faulty. this is a common problem for jettas








the ac problem is weird. Ive never heard of anything like it.

Reply:You have to connect the O.B.D. scanner and get the codes.


I think is the mass sensor, is bad.





about A/C ... the blower motor has a wire for every speed and the switch in the dash ,has each and every one connected it I venture to say ;change the dash's switch(of course, I am not sure)
