My rear fan bypass box!
#64
I will buy the Fabspeed heat bypass tube if it is made in the USA. I would rather pay a few bucks more for a part that is made here from Carbon Fiber. The rotoformed OEM tube is no nicer than cheap Rubbermade junk, cost was most likely a few bucks to make even after you factor in the Mold cost. However, if Fabspeed outsources that tube to China, I will not buy it, I refuse to buy Chinese products if I have a choice.

Fuse
Must say that I had litle doubt about wiring the two wiresin the fusebox; but it did the trick the blowers infront work. Picture of using the old parts and drilled hole for the tubes.

Great Success!
I've also just tried the jumper solution on my car. It's a MY '90 (late '89 build date) with the bypass pipe and what I believe to be the original CCU... At least idling in the driveway all of the fan speeds seem to work on full heat, which they never have before. The fan speed for the heat settings area little slower than for cold, but maybe that's just my imagination.
Thanks Guys,

I definitely experience an occasional delay in my 89 c4. It seems inconsistent, sometimes there, sometimes not. I would say it lasts a maximum of about 3-4 seconds.
If I recall correctly, the delay is only experienced if I have the heat turned up and then turn the fan on. If the fan is set to 4 and I turn the heat to a higher setting, no delay is experienced. There is no delay initially if set to full cold.
I still have my dead blower motor installed as I anxiously await the bypass tube. As you can imagine, having a gigantic unmoving fan in the way probably isn't helping things - so my airflow is pretty marginal anyway. May or may not be related.

Could be true, I've only tried this in the garage so far with the ignition on. Maybe it won't be a problem in "real life". And the hesitation is as you say maybe 2-3 seconds.

Heater bypass modification
I have had a flat battery twice in the last month sincle I installed the jumpers into the relay to make my heater bypass work.
I thought that rather than search for an alternative to my problemI would ask if anyone else experienced a battery drain since doing this modification?
