'98 TJ, 4.0L, Factory air, no previous problems.
Recently AC not blowing cold air WHEN IDLING. When moving, out on highway, etc., cools great. Stop at red light and it blows warm air. Checked freon with gauge, initially showed 40 psi then as compressor cycled, swung between 55 and 67 psi. If anything, pressure seems a tad high but freon has never been added. Wife is wanting something done. Can anybody steer me in the right direction?
