I want to START to disassemble the heater motor system this weekend. Remove the blower and the other gizmo (regulator). Can I remove these items and still run the car? I would put back the wiper system, but leave out the blower and gizmo... That way I can test the units, remove the cages, and still use my car until a new fan, etc arrives. I don't have much free time, and cannot be without the car.
Any ideas? Are they both just plug-in units that run independently of the rest of the car? 1989 300te

Pull the blower feed fuse b/c the pos side is always hot on blower system. Th switching is done on the ground side of the circuit, through the regulator.

Consider me a Dummy...where is the feed fuse? I am aware of the metal strip fuse that is separate from the fuse box... Please describe.

That's it

So, if I remove that metal strip...I am safe to go? I can then remove all the guts and still drive the car? This way I can bench test all the stuff, remove cages if necessary, and re-assemble next weekend. Will there be 'loose' ends / plugs, etc. that I will have to cover/ tape while the guts are out? Or is removing that fuse good enough?

You may want to label the wires ..I personnally would do the electrical testing in the car as everythin is hooked up .. reg test is trigger voltage from CC, blower is 12v at hot side and ground blu wire for reg by-pass to test blower

What is the blower problem??
