 98 f-150 ac sometimes works
Hi, I'm a new member and have a 98 F-150 that has an ac problem that has me frustrated. When I turn it on it blows cold, but if I give it much gas, the cold air turns into very hot air. Sometimes if I tap on the brakes and turn the ac off and on it will get cold again and may stay that way for days. Sometimes I may have to come to a stop and turn it on and off several times and it works again. Any Ideas?? and thanks |
