| I inherited a 93 Lincoln Towncar Signature series. The A/C would only work on high then it started blowing out the dash and floor vents when you accelerated but would go back to the vents when you slowed down. Now the A/C will not blow out the vents at all, it will only blow out on the dash and floor vents. I replaced the A/C heater control and it blew out the vents for about 5 minutes then started blowing out the dash and floor vents again. Any suggestions? | |

Replying to: nwraaa (Sep 07, 2008 6:40 pm) I'll be checking those a/c tools out. I'll figure out where the low pressure switch is. Would one 12oz can of freon be enough to do the color leak test for a few minutes at a time? How much time in between the 3 minute testing to be safe for the compressor? I will be checking out the areas you mentioned for the leaks. Would those areas still show signs of oil or would they be dried out by now? This is the best ? What % of any leak or the ones that you mentioned, be sealed by regular leak sealer? Does the sealer work? Would it be ok to add 2 cans of regular leak sealer to the system and would it do a better job than adding only 1 can of sealer. To what degree can a/c leaks be sealed with a/c leak sealer additives. Have you used them, have they ever worked? Is there a kind that works the best? They say that Freeze12 is very compatible with r-12 so you don't have to do alot of the prep that's needed when changing from r-12 to r-144. I haven't gotten the Freeze12 kit yet. I'm sure there is some prep, but maybe not much, other than to add the 1 can of 12oz freon, 1 can of 2oz sealer, 1 can of 2oz oil, and more freon to 40 oz. system pressure, as it says on there website. They also sell an optional heavy leak sealer to add into the system, that they say will seal larger leaks in rubber, plastic, metal, etc. But it's expensive. What is the vacuum pump needed for? Is that used to increase the system to working pressure using air instead of freon for leak testing, and for evacuating the system? You have helped alot so far on this subject. |
