1993 F-150 heater problems
Now that I fixed the A/C issue (rusted hole in the vacuum canister where that white vac lines goes to......), I have a heater issue now...It will not get warm at all....just blows cold air.....I'm thinking #1 low coolant.....#2 clogged heater core......#3 bad heater control valve (if my truck is even equipped with that). JUST CALL ME SEAN where are ya on this one bud!!!! Thank you!

Fixed it!! Looks like it was a completely clogged heater core....I have no idea how that happened but it was completely cloggled....Compressed air, water pressure wouldnt do sh*t. I just replaced it with new hoses as well. Then I filled with 2 gallons of 50/50 coolant and the rest water since I live in Florida I dont think that would be a problem. The truck should actually run cooler with the more water it has.
