1988 Wrangler , automatic trans. -- the A/C line that leads from under the radiator up to the container which houses the low pressure safety switch has ruptured due to its rubbing against an adjacent line. I plan to replace the line myself. I want to avoid the expensive dealer parts department . Can anyone steer me to a less expensive solution ? I don't know much about A/C work . I plan to have a local garage replace the old $62 per pound refrigerant with a newer $17 per pound refrigerant once I get the ruptured hose line replaced. I have been told that the switch over job will cost $200. This was detailed as $100 for 1.5 hours of labor, $39 kit, $10 dye for future leaks, 40 ounces of refrigerant $42 . Is this reasonable ?
