Re: Defrost only club need help.. 98 4.6 f150
Thats what i have been told and checked every line and replaced almost every one. As far as the reservoir, are you talking about the one thats under the fender with the four hoses or behind the battery? Those are even good and so are the hoses going to them.
I have plenty of vacuum coming into the cab and control unit, its just once i put the pedal about 1/4 to 1/2 way down while driving then thats when the air moves to the defrost.
I was looking around and someone said they had there climate control unit diagnosed by ford and it had a leak in it, He was also having the exact same problem as me, except i think he had an 03 with an electronic, and i have a manual, so i dont know if that make a difference in the diagnoses.
So I ended up buying a used one a few days again and it will be here today in about 5 hours.. Ill let you know if that doesnt work
