This is really weird. I have an "88 CRX 1.5 with A/C. Out of the blue this is what started happening. The fan blower located beneath the evaporator unit on the interior passenger side has stopped operating. The fuse is good. I have looked at all the wiring in the dash because... if the stereo is on, when I turn the blower position passed 2 it removes power to the stereo!! The radio will continue to operate if I unplug the power ro the blower at the blower itself. This may be a simple solution to someone. Please advise. Thx

 

sounds like someone wired the stereo in series with the blower?

 

That's what I thought. I pulled the dash. Nope.

 

is the factory stereo plug still intact?

IM or PM me if you wish---we had a similar problem with my buddy's '87 teg

...looking at '88 CRX wiring diagrams...

I was looking at the wiring diagram in the maintenance manual... and there appears to be a common wire between the radio and the blower. I was thinking if the blower has gone bad, when turned on perhaps it is grounding-out the source to the radio? I cannot get the blower to come on at all (switch ON, Acc, or running).

 

both wires are white and blue for power

the blower is a high-current accessory--have you checked the fuse box for burnout?

check the blower-as you are thinking-for dead shorts.

man--stereo installations and battery movers seem to have caused most of the electrical woes that we have seen!

we solved the problem in the 'teg by changing the fuse block; it had a burnt spot (which created a poor connection). afterwards the stereo and blower worked fine together

 

my car did this, it was the ignition switch.


heres the how-to i did

sometimes the contacts are so worn a rebuild doesn't help, though.

 

Yours did the same funky thing with the fan blower, too????

 

It IS the switch on the steering column. Very touchy. Position it just right... all works properly. I know what I'll be doing when I have a few hours. Thanks a million!!!!!

 

yes. the blower began drawing too much current through a bad connection in the fuse block...the stereo didnot have but 8 volts on it while the blower was set to II or above. when the blower was off, the [stock] stereo worked fine. power amps and other auxilliary stereo equipment cannot run from this power tap.

 

pulling the steering wheel off? new switch.

 

Yeh... But I'll check for corrosion first, though.
