Bypassing heater core and a/c problems
Since I live in Texas and won't be needing my heater for awhile, I've decided to bypass the heater core since I've had to replace it 5 times in less than 2 years, any precautions I should take while it's bypassed?
And 2nd question is on my a/c, had it charged by the dealer and next day the line busted apart on the high side, so instead of wasting another $100 I just went and bought a can from auto zone and it's got about 1psi pressure and blows cold(not as cold as full charge) but passenger isn't as cold as drivers side. Maybe too much head pressure?? Wanting better a/c cuz black leather and Texas weather make for a hot ride

what yr blend doors known to break and possible orifice tube clogged lo side pressure will usually go up when clogged tube been known to get clogged.depending on yr orifice tube
in line fron drier to evaporator goes behind battery on r/s.tube not replaceable have to replace line if that is problem.

Don't Shut It Completely Off
Make sure you actually "bypass" it and don't just shut it off. You can either plumb in a bypass with a core shutoff valve on the existing lines, or tap another port on the back of the head for your bypass. But whatever you do, make sure to maintain water flow out the back of that head.

It's an '03 and at the end of the summer last year, I had to replace almost all the blend doors and actuators which sucked, and how Would I check to make sure the lines aren't clogged? Or would I just have to replace the line? And on the heater I piped in a new line to bypass the heater core. Idk why they keep failing? No bubbles and not over pressuring, I've heard some people saying something about electrolysis, and putting a zinc diode on the line to absorb the electrical charge.

Use a temp gun at the orfice; should be a major temperature difference before and after as that's what creates the area of low pressure and allows the refrigerant to boil. No major temp difference could indicate your plug (if any). Should see 4 small indents or flat spots around the high side compressor line; that'll be where your orfice is at.

Also if the system opened to atmosphere, it's now considered contaminated and most shops won't touch it anyways (that is if they test it before recovery) best bet; figure out the problem; take the valve core out of the low side and let it sit over night allowing it all to evaporate. Replace your receiver/dryer and have an a/c shop or friend vac it down.
