I have a 1987 560 SL. The problem is that the blower was only working on low and climate control , but not on high. Then the fuse blew. This happened previously and then I put in a newly rebuilt pushbutton control and it happened soon after installation. Thanks in advance for any help on this.

I remember having a similar problem with my climate control switches, except my blower wouldn't work under any circumstance. I would turn the unit on and after several minutes the fuse would blow. I took a gamble and purchased a new blower motor, installed it and problem solved. Everything works perfect and no blown fuses in over a year.
If you're very handy several shops sell rebuild kits cheaply. The kits include brushes which is usually the problem with these motors. Do a search on this site.
I truly didn't understand if after you installed the rebuilt switch, the high setting worked for a short while or if the fuse blew after a short while. If the blower worked for a short while, your problem may lie elsewhere. If the high setting didn't work at all after the new switch and then blew a fuse, chances are you need a new blower.

Good Luck

Thanks for the reply, The blower did not work on high. Only low and climate control.

does it work on defrost? defrost should make it work on high, its a default setting.

Someone also told me that it might be the blower regulator.

I am am still having this problem. The blower works now with climate control, but not on high or low. It eventually blows a fuse. Does anybody know what causes this?
