I've still got some electrical gremlins to work out. Windshield wipers won't park or do a full mist sweep. Passenger window is sticking going up, there is multiple rattles going on, I have a air leak somewhere into the driver's side foot well, the auto rear view mirror doesn't work, the front windshield needs to be replaced, it still clunks in the front end, the driver's side seat track has slop in it, rear wiper doesn't work, brakes are hard one second and soft the next.
So its a 98 Explorer, sounds to be in good shape! LMFAO
1. Wipers = multi function switch
2. Pass window, I bet you find the metal track dealio has come loose, they break their mount for the bolt. A quick weld or replacement, remove door panel have look see
3. Rattles = 1998 was a while ago
4. Air leak = new door seal, can swap with passenger side in a pinch
5. Windshield = Shop around can get installed around $150-180, the glass costs installers $65 so make them fight for your business
6. Auto dimmer mirror, autolights, I hate those things!! I always remove and upgrade
7. Front end clunk = what SLA IFS Ford doesnt have a clunk? all is normal here move along (Usually sway bar bushings or ball joint)
8. Brakes hard and soft = check to see booster is holding vacuum, any leaks in the brake system? fluid loss?
New flowmaster = Nice to see you have repairs going in proper order. With the new muffler you can ignore items 3, 4, 6, 7, and possibly 2, maybe 1 and heck it still stops so 8 too......
