sorry , but if it is low refrigerant as you say...
when it works it will give hot air all the way...
thanks

If it's only a little low it can do what you describe

Yes this is why I said it could be low. It doesn't take much loss to blow warm air. If its too low I don't think the compressor will come on. If the compressor comes on then its not terribly low.

I just recharged my Fit. Was blowing hot air but compressor was kicking on. Just needed a recharge and she is blowing ice cold!!

Thats exactly right... if freon is too Low it will not trigger A/C compressor to go on ( You wont hear the Click vroom on/off from Compressor ) had this problem with wifes Nissan murano if your doing it yourself You need to jump start the A/C compressor 1st into thinking it has freon done by jump wiring A/C compressor in order to suck in and re-fill it useing off the shelf stuff in a can thats what i was told by my mechanic.

Also take Note. if Your planning on keeping this Vehicle for a short time? off the shelf synthetic versions of R134 are ok to-do but if your keeping it for a Long time its NOT advisable to use after market quick fills in a can (reason being i was told ? is the make up of the chemistry is just not as good to use as the real original R134 sold commercially to vehicles got it.)
