Heater Blower issue please HELP

Hi All,

about a month ago my heater switch stopped working so i bought a switch from GSF/Euro car parts (they are both the same tried both). now my original switch had 3 speeds. the new one has a 4th speed which switches off the heater. heater works on speeds 1-3.

now my problem is that on that it does not clear my front glass i do not know whether this is due to the switch or something to do with the heater resistor. the blower just does not seems to be powerful enough.

i replace the heater blower about a year ago when taking it out it spins fine doesn't seem restricted.  When but putting my hand below the blower its not powerful so there is nothing from stopping the air.

any help is much appreciated

thanks in advance

Assuming air is coming out the dash vents then try a dash vent kit from Crazyquiff, that will help
